Viscosity, while not as impactful on flow as radius, still is an important factor that alters blood flow rates in the body. Dehydration as well as other pathological conditions that alter the viscosity of blood could have detrimental impacts on the body. I am unsure of how to do a proper video demonstration or even a drawing of viscosity, so we are going to stick with a good old fashioned written description for this one. I’d like to demonstrate that blood is in fact, thicker than water which would alter rate of flow. We’ll assume η=1cP for water and η=5cP for blood. With constant pressure- ΔP, r=2cm and l=10cm

Water: Q = ΔP (π (2cm4)/8(1cp)(10cm)

Q= ΔP (π*16)/ 80 Q= ΔP 50.27/80 Q= .63

Blood: Q = ΔP (π (2cm4)/8(5cp)(10cm)

Q= ΔP (π*16)/400 Q= ΔP 50.27/400 Q= .13

If pressure is constant, as viscosity increases, resistance increases, and therefore flow decreases. With our increase in viscosity from water to blood by about 5x, we see about a 5x decrease in flow, modest compared to the exponential decrease in flow as radius decreases. Interestingly, as blood vessel radius decreases however, the viscosity of blood in the body decreases, partly due to the increase in velocity, "shear thinning" is the decreased viscosity seen by faster moving blood.

Part A

Describe how tube radius might influence the flow rate in their demonstration. How would you have to manipulate your variable (increase/decrease) to make the flow rate equal between the two examples. For example, if I want to have equal flow through my two different straw lengths, I could decrease pressure through the short straw until the Flow rate was equal to that of the long straw.

Part B

Based on your manipulation, how would this affect cardiac output if you imagine your classmate's example is the vascular bed? Would cardiac output increase or decrease? Why?

Answers

Answer 1

Part A The radius of the tube is a factor that determines the flow of fluid through it. The flow rate of a liquid through a tube is proportional to the fourth power of the radius and inversely proportional to the viscosity of the fluid. Thus, the flow of blood through a blood vessel is affected by its diameter (radius).

Part B In order to maintain the same flow rate in both tubes, the pressure in the tube with the smaller diameter must be increased. If we imagine our classmate's example as the vascular bed, this would reduce cardiac output. Cardiac output is the amount of blood pumped out by the heart in one minute. It is determined by heart rate (HR) and stroke volume (SV), which is the amount of blood pumped out of the heart in one beat.

If we consider the smaller diameter of the tube as a blood vessel, its diameter can affect the flow of blood and, therefore, the cardiac output. A decrease in the radius of the blood vessel will result in an increase in resistance, which will require more pressure to maintain the same flow rate. If the pressure in the tube is increased to maintain the same flow rate, this would reduce cardiac output.

The speed of a 20Hp, 300V, 2500rpm separately excited de motor is energized from a 208V, 60Hz, 3-phase source through 3 phase full converter. The field current is set to the maximum value. The de motor parameters are as under; ra-0.50, Km 0.8 V-s/rad, La-10mH. Rated armature current-210A. No-load armature current 10% of rated current. Armature current is continuous and ripple free. Calculate: Delay angle of armature converter if the motor supplies rated power at the rated speed.

Answers

The delay angle of the armature converter if the motor supplies rated power at the rated speed is 2.2 degrees.

In order to solve the problem, it is important to understand that the power output of a motor is given by: Pout = V x I x power factor x efficiency Where V is the supply voltage to the motor, I is the current flowing through the motor, power factor is the ratio of real power to apparent power, and efficiency is the ratio of mechanical output power to electrical input power. Now, the given motor parameters are as follows: Power rating = 20 HP Voltage rating = 300 V Speed rating

= 2500 rpm Armature resistance

= 0.5 Ohm Back emf constant

= 0.8 V-s/rad Armature inductance

= 10 mH Rated armature current

= 210 A No-load armature current

= 10% of rated current Armature current is continuous and ripple free.

Using these parameters, we can calculate the armature current under rated conditions: Power rating = 20 HP

= 14.92 kWI

= Pout / (V x power factor x efficiency) Efficiency can be assumed to be 0.9 for this type of motor, and power factor can be assumed to be 0.8. Thus, I = 14.92 / (300 x 0.8 x 0.9)

= 69.5 A Therefore, the armature current under rated conditions is 69.5 A. The delay angle of the armature converter is given by: sin(delay angle) = [tex](V - Eb) / (sqrt(2) x Eb x ra x I)[/tex] where V is the supply voltage, Eb is the back emf of the motor, ra is the armature resistance, and I is the armature current. Under rated conditions, the motor is supplying 20 HP at 2500 rpm, so we know that: Pout = 20 HP

= 14.92 kWEb

= Km x omega

= 0.8 x 2500 x 2pi / 60

= 209.4 V Substituting these values, we get:

[tex]sin(delay angle) = (300 - 209.4) / (sqrt(2) x 209.4 x 0.5 x 69.5)[/tex]

= 0.0383 Therefore, the delay angle of the armature converter is:

delay angle = arcsin(0.0383)

Answers

The statement "Unsaturated means that each C atom is bonded to four other atoms (H or C)-the most possible; there are no double or triple bonds in the molecules" is False.

What is meant by an unsaturated compound?

An unsaturated compound is a chemical compound in which at least one double or triple bond exists between carbon atoms. These bonds may be between two carbon atoms or between a carbon atom and another element, such as oxygen or nitrogen, and they create a region of unsaturation in the molecule. In chemistry, the term unsaturation is used to describe the number of multiple bonds present in a molecule. The more unsaturated a molecule is, the more double and triple bonds it contains. Molecules with no multiple bonds are referred to as saturated because each carbon atom is linked to four other atoms (usually hydrogen).

This means that Unsaturated doesn't mean that each C atom is bonded to four other atoms (H or C)-the most possible, and there are no double or triple bonds in the molecules. Therefore, the correct option is (b) False.

When calculating the equivalent resistance for a thevenin's equivalent circuit, do you count in your calculations the resistors that have no current going through? why?

Answers

When calculating the equivalent resistance for a Thevenin's equivalent circuit, we do not include the resistors that have no current flowing through them.

In the calculation of the Thevenin's equivalent resistance, only the resistors that have current flowing through them are considered. Resistors that have no current passing through them are effectively open circuits and can be excluded from the calculation. The reason for this is that when there is no current flowing through a resistor, it does not contribute to the overall resistance of the circuit. In other words, it does not affect the flow of current or the voltage across the circuit.

The Thevenin's equivalent circuit is a simplified representation of a complex circuit, which includes a single equivalent voltage source and an equivalent resistance. The purpose of this simplification is to analyze and predict the behavior of the circuit when connected to external components. By considering only the resistors that have current flowing through them, we accurately capture the effective resistance that influences the current flow and voltage distribution in the circuit.

Therefore, when calculating the equivalent resistance for a Thevenin's equivalent circuit, we do not include the resistors that have no current flowing through them. These resistors are effectively ignored since they do not impact the overall behavior of the circuit.

The two radii that need to be determined are the radius of the driving wheel and the radius of the conveyor belt drum, given that the canisters are centered 200 mm apart on the conveyor belt and the stamp S is located on the revolving drum such that it is used to label the canisters.

The formula for determining the radius is:r = L/2 + (D^2 + L^2)/(8L), where L is the distance between the centers of the two canisters and D is the diameter of the revolving drum. The radius of the conveyor belt drum is:r1 = L/2 + (D^2 + L^2)/(8L)= 200/2 + (200^2 + 200^2)/(8*200)= 100 + 20000/1600= 112.5 mm ≈ 0.1125 m.

Cesium-137 decays into Barium-137 by beta decay. The electrons emitted by the radioactive decay of Cesium-137 have an energy of 1.17 MeV = 1.17 x 106 eV. The molar mass of Cesium-137 is 136.91 g/mol, the half-life of Cesium-137 is 30.2 years, and Avogadro's number is 1 mole = 6.022 x 1023 particles. The RBE factor of these electrons is 1. The number of seconds in a year is 3.154 x 107 sec.

(e) What is the equivalent dose received by Person 2, 1 year after the Chernobyl disaster, from the ra- dioactive decay of Cesium-137?
(f) Let's define your answer from part (e) as EDCesium. The maximum allowed radiation level for a radiation worker in a year is EDsafe= 0.02 Sv. What is the value of the ratio ED Cesium/ED safe? This number will tell us how many times larger the equivalent dose from part (e) is, as compared to a safe equivalent dose.

Answers

(a) The initial mass of Cesium-137 released to the environment in Pripyat after the Chernobyl disaster can be calculated to be approximately 1.37 kg.

(b) It will take approximately 22.8 years for the activity to drop to a much safer level of 10 decays/sec in Pripyat.

(a) To determine the initial mass of Cesium-137 released, we can use the activity and the half-life of Cesium-137. The equation N(t) = N₀ * (1/2)^(t/T) relates the number of radioactive atoms at a given time (N(t)) to the initial number of atoms (N₀), the time elapsed (t), and the half-life (T). Rearranging the equation to solve for N₀, we have N₀ = N(t) * (2)^(t/T). Substituting the given values, N(t) = 1 x 10^13 decays/sec and T = 30.2 years, we can calculate N₀. Since Avogadro's number tells us that 1 mole of a substance contains 6.022 x 10^23 particles, we can convert N₀ to the initial mass of Cesium-137 by multiplying by the molar mass of Cesium-137, which is 136.91 g/mol. Thus, the initial mass of Cesium-137 is approximately 1.37 kg.

(b) To calculate the time required for the activity to drop to 10 decays/sec, we can use the decay equation N(t) = N₀ * (1/2)^(t/T), where N(t) is the current number of radioactive atoms. We need to solve for t. Substituting N(t) = 10 decays/sec, N₀ = 1 x 10^13 decays/sec, and T = 30.2 years, we can solve for t. Taking the logarithm of both sides of the equation, we have t = T * log₂(N(t)/N₀). Substituting the given values, we find that t ≈ 22.8 years.

In an adiabatic process, the temperature of the system may change as work is done on or by the system, but there is no heat transfer. Adiabatic processes are commonly found in engines, such as the compression and expansion processes in internal combustion engines.

b. A closed system is a thermodynamic system that does not allow the transfer of matter with its surroundings, but it can exchange energy in the form of heat or work. The boundaries of a closed system are impermeable to matter, meaning that no mass can enter or leave the system. However, energy can be exchanged in the form of heat or work through the system's boundaries. An example of a closed system is a sealed container where a chemical reaction takes place, allowing heat to be transferred between the system and its surroundings while keeping the number of particles constant.

c. One similarity between an isothermal system and an adiabatic system is that both involve changes in a system's internal energy. In an isothermal system, the temperature remains constant throughout the process, resulting in no change in the internal energy. In contrast, an adiabatic system may experience a change in temperature, leading to a change in the internal energy. The difference between the two lies in the transfer of heat. In an isothermal process, heat transfer occurs to maintain the constant temperature, while in an adiabatic process, there is no heat transfer.

d. One similarity between an open system and a closed system is that both systems allow for the exchange of energy with the surroundings. In an open system, not only can energy be exchanged, but there can also be a flow of matter across the system's boundaries. This means that mass can enter or leave the system. On the other hand, in a closed system, there is no transfer of matter across the boundaries, but energy can still be exchanged. Both open and closed systems exhibit the capability of energy exchange, although open systems provide an additional avenue for the exchange of matter.

(i) The reactions for the two decays are:

For 89% of 40K decays:

40K → 40Ca + e- + v1840Ca has 20 protons and 20 neutrons, so the mass number is 40.40K and has 19 protons and 21 neutrons, so the mass number is also 40.For 11% of 40K decays:

(ii) For the decay to 2040Ca: The reaction order is first order. Thus, t1/2 = 0.693/k where k is the decay constant. To calculate k:

40K is decreasing by 0.693 units every 1.25 x 109 years. We can use that fact to calculate the decay constant:

k = 0.693 / (1.25 x 109)k = 5.54 x 10-10 (years)-1Thus, t1/2 for decay to

2040Ca: t1/2 = 0.693 / 5.54 x 10-10 (years)t1/2 = 1.25 x 109 years or the decay to

k:40K is decreasing by 0.693 units every 1.25 x 109 years. We can use that fact to calculate the decay constant:

k = 0.693 / (1.25 x 109)k = 5.54 x 10-10 (years)-1

The decay to 1840Ar proceeds through electron capture, which involves the absorption of an electron rather than the emission of a positron (e+). the decay rate for the decay to 1840Ar will be the same as that for the decay to 2040Ca.

A pendulum has a length of 1.12 m. What is the period of this pendulum? Express your answer to two significant figures and include the appropriate units.

Answers

The period of the pendulum with a length of 1.12 m is approximately 2.12 seconds.

The period of a pendulum can be calculated using the formula:

T = 2π√(L/g)

where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity.

Length of the pendulum (L) = 1.12 m

The acceleration due to gravity (g) is approximately 9.8 m/s².

Calculating the period of the pendulum:

T = 2π√(1.12/9.8)

T ≈ 2π√(0.1143)

T ≈ 2π(0.338)

T ≈ 2.12 seconds

1. If a motor generates a sound pressure of 4.3 Pa, calculate the sound pressure level in decibels.

2. A worker is exposed to noise levels of 80 dBA for 60 minutes, 84 dBA for 120 minutes and a background level of 70 dBA for the remainder of their 8 hour shift. Calculate their 8 hour noise exposure.

3. Define the term ‘primary aerosol’. List three examples of a primary aerosol.

Answers

The sound pressure level in decibels is 58 dB

We know that Sound Pressure Level (SPL) is the ratio of the sound pressure to the reference pressure, multiplied by 20. The formula for calculating SPL is given below:

SPL = 20 log10 (P/P0)

Here, P = 4.3 Pa and P0 = 20 x 10^-6 Pa (reference pressure)

Therefore, SPL = 20 log10 (4.3/(20 x 10^-6))

= 20 log10 (215000)= 20 x 5.332

= 106.64 dB

≈ 58 dB2.

The worker's 8-hour noise exposure is 81.1 dBA

We know that the noise exposure level can be calculated using the following formula:

Noise Exposure (L)= (T1/L1) + (T2/L2) + (T3/L3)

Where,T1 = duration of exposure at level L1T2 = duration of exposure at level L2T3 = duration of exposure at level L3L1, L2, L3 = noise levelsW

e are given that T1 = 60 min, L1 = 80 dBA,

T2 = 120 min, L2 = 84 dBA, T3 = 8 hours - (60 min + 120 min)

= 6 hours = 360 minutes,

L3 = 70 dBA

Therefore,

Noise Exposure (L)= (60/80) + (120/84) + (360/70)

= 0.75 + 1.43 + 5.14= 7.32

Total noise exposure = 7.32

Therefore, the worker's 8-hour noise exposure is 81.1 dBA.3.

Answers

a) Moore’s Law is a prediction that was first made by Gordon Moore, the co-founder of Intel Corporation, in 1965. The law suggests that the number of transistors that can be placed on a computer chip will double every two years, while the cost of manufacturing the same will halve.

This has led to the incredible growth in the computing industry and has allowed for the development of smaller, more powerful devices at a cheaper cost. Moore’s Law has been highly successful in the advancement of electronics because it has acted as a guide to technology developers and has provided a framework for their research and development. With the understanding that the number of transistors would double every two years, developers have been able to set achievable goals that have allowed them to achieve this prediction. This has led to the development of ever-more powerful computer chips that have revolutionized the way that people live and work.

b) A Metal-Oxide-Semiconductor (MOS) capacitor is a type of capacitor that is commonly used in electronic circuits. The MOS capacitor consists of a metal electrode, a semiconductor substrate, and an oxide layer that separates the metal electrode from the substrate. The MOS capacitor is used to store charge and to control the flow of current in a circuit.

There are two types of MOS capacitors: the depletion-mode MOS capacitor and the enhancement-mode MOS capacitor. The depletion-mode MOS capacitor is normally on, which means that it conducts current when no voltage is applied to it. The enhancement-mode MOS capacitor, on the other hand, is normally off, which means that it does not conduct current until a voltage is applied to it.

The MOS capacitor is an important component in many electronic circuits because it allows for the precise control of charge and current flow. It is widely used in digital circuits, where it is used to store charge and to control the switching of current between different circuits.

Imagine a uniform magnetic field, pointing in the z direction and filling all space (B = Bo 2). A positive charge is at rest, at the origin. Now somebody turns off the magnetic field, thereby inducing an electric field. In what direction does the charge move?

Answers

A long answer to the given question is as follows:A uniform magnetic field fills all the space pointing in the z direction with a strength of B = Bo 2.

There is a positive charge which is stationary and placed at the origin. When the magnetic field is turned off, an electric field is induced. The direction in which the charge moves can be determined by using Fleming's right-hand rule. The rule states that when the thumb, index finger, and middle finger of the right hand are all mutually perpendicular, then the thumb points in the direction of the force (F), the index finger points in the direction of the magnetic field (B), and the middle finger points in the direction of the motion (v)

According to the given problem statement, the magnetic field is turned off, and an electric field is induced. Due to this electric field, the positive charge will experience an electric force which is perpendicular to the magnetic field. Now, according to the Fleming's right-hand rule, the electric force will be in the direction of the thumb. Therefore, the charge will move in the direction of the electric force, which is perpendicular to the magnetic field, i.e., in the xy-plane.

c) What is the concentration of holes in the valence band (nn)?
d) Calculate if a photon with a wavelength of 1550 nm will be absorbed by an GaSb photodiode. Explain your result.

Answers

a) The modified Fermi energy at 300 K for GaSb is approximately 0.7592 eV, b) The effective density of states for holes in the valence band (Ny) is approximately 1.61 x 10^18 cm^-3, c) The concentration of holes in the valence band (nn) is approximately 2.43 x 10^16 cm^-3 and d) A photon with a wavelength of 1550 nm will not be absorbed by a GaSb photodiode since its energy (0.8008 eV) is lower than the bandgap energy (0.75 eV) of GaSb.

a) The modified Fermi energy (E_f) can be calculated using the equation:

E_f = E_g + (3/4)kT * ln(m_h/m_e)

where E_g is the bandgap energy, k is the Boltzmann constant (8.617 x 10^-5 eV/K), T is the temperature in Kelvin, and m_h and m_e are the effective mass of holes and electrons, respectively.

Substituting the given values:

E_g = 0.75 eV

m_h = 0.4 me (effective hole mass)

m_e = 0.042 me (effective electron mass)

T = 300 K

E_f = 0.75 eV + (3/4) * (8.617 x 10^-5 eV/K) * 300 K * ln(0.4/0.042)

Calculating E_f:

E_f ≈ 0.75 eV + 0.0092 eV ≈ 0.7592 eV

Therefore, the modified Fermi energy for GaSb at 300 K is approximately 0.7592 eV.

b) The effective density of states for the holes in the valence band (N_y) can be calculated using the equation:

N_y = 2 * (2π * m_h * k * T / h^2)^(3/2)

where m_h is the effective hole mass, k is the Boltzmann constant, T is the temperature in Kelvin, and h is the Planck's constant (4.136 x 10^-15 eV·s).

Substituting the given values:

m_h = 0.4 me

k = 8.617 x 10^-5 eV/K

T = 300 K

N_y = 2 * (2π * 0.4 * 8.617 x 10^-5 * 300 / (4.136 x 10^-15))^1.5

Calculating N_y:

N_y ≈ 1.61 x 10^18 cm^-3

Therefore, the effective density of states for the holes in the valence band (N_y) is approximately 1.61 x 10^18 cm^-3.

c) The concentration of holes in the valence band (n_n) can be calculated using the equation:

n_n = N_y * e^(-E_f / (k * T))

where N_y is the effective density of states for the holes, E_f is the modified Fermi energy, k is the Boltzmann constant, and T is the temperature in Kelvin.

Substituting the given values:

N_y = 1.61 x 10^18 cm^-3

E_f = 0.7592 eV

k = 8.617 x 10^-5 eV/K

T = 300 K

n_n = 1.61 x 10^18 * e^(-0.7592 / (8.617 x 10^-5 * 300))

Calculating n_n:

n_n ≈ 2.43 x 10^16 cm^-3

Therefore, the concentration of holes in the valence band (n_n) is approximately 2.43 x 10^16 cm^-3.

The time spent parked was approximately 2 hours and 31 minutes.

Starting in Albany, you travel a distance of 347 miles in a direction 21.3 degrees north of west. Then, from this new position, you travel another distance of 449 miles in a direction 21.1 degrees north of east. In your final position, the displacement from Albany can be calculated by first determining the horizontal and vertical components of the two distances traveled and adding them up to find the resultant displacement.

Using trigonometry: Horizontal component of first distance = 347 cos(21.3) = 321.7Vertical component of first distance = -347 sin(21.3) = -124.2Horizontal component of second distance = 449 cos(21.1) = 420.6Vertical component of second distance = 449 sin(21.1) = 163.1The horizontal displacement is found by adding

The two horizontal components: Horizontal displacement = 321.7 + 420.6 = 742.3 miles.

The vertical displacement is found by adding the two vertical components: Vertical displacement = -124.2 + 163.1 = 38.9 miles.

The resultant displacement can be found using the Pythagorean theorem: Resultant displacement = √(742.3² + 38.9²) ≈ 742.6 miles.

The angle of the resultant displacement can be found using the tangent function:θ = tan⁻¹(38.9/742.3) ≈ 2.99° north of we therefore, the answer is 742.6 miles, 2.99 degrees north of west.2.

The average velocity for the entire trip was 19.89 miles per hour to the south. Let the time spent parked be t. Using

The formula for average velocity:v = d/t where d is the total distance traveled and t is the total time taken.

We can create an equation to relate the different variables:v = (109 + 24)/(2 hours 41 minutes + t + 2 hours 40 minutes)19.89 = (109 + 24)/(4 hours 21 minutes + t)

Multiplying both sides by the denominator:19.89(4 hours 21 minutes + t) = 133Simplifying:82.69 + 19.89t = 133Subtracting 82.69 from both sides:19.89t = 50.31Dividing by 19.89:t ≈ 2.52 hours or 2 hours and 31 minutes.

[Double slits with finite width] In a double-slit Fraunhofer diffraction experiment, so-called "missing orders" occur at those values of sinθ that simultaneously satisfy the condition for interference maxima and the condition for diffraction minima. Show that this leads to the condition d /a = integer, where a is the slit width and d is the distance between slits. Derive the approximate relation d sinθ = mλ as the condition for interference maxima. Use the results above to show that the number of interference maxima under the central diffraction maximum of the double slit diffraction pattern is given by 2d/(a-1) , where a is the slid width and d is the distance between slits.

Double slits with finite widthIn a double-slit Fraunhofer diffraction experiment, the "missing orders" occur when sinθ satisfies the condition for both interference maxima and diffraction minima. This leads to the condition d /a = integer.

In a double-slit Fraunhofer diffraction experiment, "missing orders" occur at those values of sinθ that simultaneously satisfy the condition for interference maxima and the condition for diffraction minima.

This leads to the condition d/a = integer, where a is the slit width and d is the distance between slits. This condition is known as Rayleigh's criterion. The condition for interference maxima is given by d sinθ = mλ, where m is an integer. Derive the approximate relation for this condition.

Using small angle approximation and applying the Taylor series, we can approximate the above expression to obtain the following relation:

d sinθ ≈ mλ or sinθ ≈ mλ / d.

The number of interference maxima under the central diffraction maximum of the double-slit diffraction pattern is given by 2d / (a-1) where a is the slit width and d is the distance between slits.
