Answer: -8.51 ft^3/lbm
Explanation:
In this question, to find the change in volume, we will use the ideal gas law.
[tex]\begin{aligned}&n_{1}=1 \text { mole }\\&\mathrm{P}_{1}=20 \mathrm{psia}\\&\mathrm{T}_{1}=70^{\circ} \mathrm{F}\\&T_{1}=(70+460)^{0} \mathrm{R}\\&v_{1}=\frac{\left(0.3704 \frac{psia \cdot_{\text { } ft^{3}}}{l \mathrm{lbm} \cdot R}\right)(70+460)^{0} \mathrm{R}}{20 \mathrm{psi}}\\&v_{1}=9.816 \frac{\mathrm{ft}^{3}}{\mathrm{lbm}}\end{aligned}[/tex]
[tex]\begin{aligned}&\mathrm{n}_{2}=1 \text { mole } \\&\mathrm{P}_{2}=150 \mathrm{psia} \\&\mathrm{T}_{1}=\mathrm{T}_{2}=70^{0} \mathrm{~F} \\&\mathrm{~T}_{1}=\mathrm{T}_{2}=(70+460)^{0} \mathrm{R} \\&v_{2}=\frac{\left(0.3704 \frac{\text { psia} \cdot \mathrm{ft}^{3}}{\mathrm{lbm} \cdot R}\right)(70+460)^{0} \mathrm{R}}{150 \mathrm{psi}} \\&v_{2}=1.309 \frac{\mathrm{ft}{ }^{3}}{\mathrm{lbm}}\end{aligned}[/tex]
[tex]$$The change in volume is,$$\begin{aligned}&\Delta v=v_{2}-v_{1} \\&\Delta v=1.309-9.816 \\&\Delta v=-8.51 \frac{\mathrm{ft}^{3}}{\mathrm{lbm}}\end{aligned}\text{The negative sign shows that the gas was compressed during this process}[/tex]

Six 20 watt, 12-volt luminaires (lighting fixtures) are supplied from a small, 12-volt transformer that is 60 feet away from the fixtures. the wire used is 14 awg. what is the voltage applied to the fixtures? use k = 11.6.
If the wire used is 14 awg. The voltage applied to the fixtures is: 8.61 volts.
Voltage applied to the fixturesFirst step is to calculate the amperes using this formula
I = P ÷ E
Where:
I =load current (amperes)=?
P =Product of voltage=(6)(20)
E =Electrical circuit's=12
Let plug in the formula
I= (6)(20) ÷ 12
I=120÷12
I= 10 amps
Second step is to calculate the Voltage drop
Using this formula
Vd = [2KIL] ÷ CMA
Where:
Vd= Voltage drop( volts)=?
K=Direct current constant=11.6
I=Load current (amperes)= 10 amps
L =Length in feet=60 feet
CMA=Circular mill area= 4110
Let plug in the formula
Vd= [(2)(11.6)(10)(60)] ÷ 4110
Vd=13,920÷4110
Vd= 3.3869 volts
Third step is to calculate Voltage at fixture
Voltage at fixtures=Electrical circuit's-Voltage drop
Voltage at fixtures=12 - 3.3869
Voltage at fixtures=8.6131 volts
Voltage at fixtures=8.61 volts (Approximately)
Therefore the voltage applied to the fixtures is: 8.61 volts.

A bakery wants to determine how many trays of doughnuts it should prepare each day. Demand is normal with a mean of 15 trays and standard deviation of 5 tray. If the owner wants a service level a at least 95%?
The number of trays that should be prepared if the owner wants a service level of at least 95% is; 7 trays
How to utilize z-score statistics?We are given;
Mean; μ = 15
Standard Deviation; σ = 5
We are told that the distribution of demand score is a bell shaped distribution that is a normal distribution.
Formula for z-score is;
z = (x' - μ)/σ
We want to find the value of x such that the probability is 0.95;
P(X > x) = P(z > (x - 15)/5) = 0.95
⇒ 1 - P(z ≤ (x - 15)/5) = 0.95
Thus;
P(z ≤ (x - 15)/5) = 1 - 0.95
P(z ≤ (x - 15)/5) = 0.05
The value of z from the z-table of 0.05 is -1.645
Thus;
(x - 15)/5 = -1.645
x ≈ 7

when electric power is transmitted over long distance, line losses can be reduced by generating AC rather than DC voltage and by transmitting?
When electric power is transferred over a long distance then, line loss can be reduced by high voltage and low current. Thus, option A is correct.
What is electric power?The complete question is attached to the image below.
The electric circuit transfers the electric current then it is called electric power. The loss in the line over a larger distance is reduced by transferring AC instead of DC voltage.
The AC transmitted is of high voltage, and the power is low. The equation for current is given,
P = VI
The increase in the voltage causes the decrease in the current and in turn the resistance also reduces resulting in the loss of the power of the circuit to decrease.
Therefore, the loss is reduced by transferring high voltage and, low current AC.

Besides hev and ev motor systems themselves what other systems may use high voltage
Besides hev and ev motor systems themselves what other systems may use high voltage are the air conditioning compressor, auxiliary battery, and water pump.
Why an excessive voltage is used?
High voltages are utilized in transmission structures due to the fact a better voltage implies a decrease modern-day for a given energy of transmission. With a decrease modern-day, much less warmth is generated withinside the transmission traces and so much less electricity is wasted. Furthermore, it has superb environmental benefits.
To come up with a difficult estimate the common rated energy of the water pump is from 250 watts to 1500 watts. The smaller the water pump, much less is the wattage, much less is the energy consumption, subsequently low is the release and head.Usually, an auxiliary deliver is energy delivery that gives an auxiliary voltage.

C) recovers refrigerant in a non-pressurized container. D) can only be performed on a system with an operating compressor.
Answer:
C) recovers refrigerant in a non-pressurized container
The system dependent (passive) recovery process recovers refrigerant in a non-pressurized container. The correct option is C.
A way of recovering refrigerant from a system without using a pump or heat is known as a system-dependent (passive) recovery process.
Instead, it relies on the system's normal pressure and temperature variations to speed up the recovery process.
A non-pressurized container is commonly connected to the system using this technique, and the refrigerant is then passively allowed to flow inside the container.
The system-dependent recovery procedure, according to Option C, recovers refrigerant in a non-pressurized container.
It entails that the refrigerant is gathered in a container without the need of a pump or additional pressure.
Thus, the correct option is C.
