Answers

Answer 1

Molar Flow Rate of Ethene,  Dry Air and Carbon Dioxide = 0.3577 mol/s

Molar Flow Rate of Water = 0.3577 mol/s * (2 mol H₂O/1 mol C₂H₄) = 0

What is Molar Flow Rate ?

Molar flow rate is the volumetric flow rate of a fluid divided by the molar mass of the fluid. It is typically expressed in moles per second (mol/s). It is a measure of the amount of a substance passing through a given surface area per unit time.

H₄ Molar Flow Rate of Ethene = 10.0 kg/s * (1 mol/28.05 g) = 0.3577 mol/s

Molar Flow Rate of Dry Air = 0.3577 mol/s * (1 mol C₂H₄/1 mol O₂) = 0.3577 mol/s

Volumetric Flow Rate of Air = 0.3577 mol/s * (22.4 L/mol) * (1 m3/1000 L) = 0.00801 m3/s

Average Molar Mass of Air = (0.7820 mol N₂ * 28.01 g/mol) + (0.2090 mol O2 * 32.00 g/mol) + (0.0090 mol Ar * 39.94 g/mol) = 28.99 g/mol

Molar Flow Rate of Carbon Dioxide = 0.3577 mol/s * (1 mol CO₂/1 mol C₂H₄) = 0.3577 mol/s

Molar Flow Rate of Water = 0.3577 mol/s * (2 mol H₂O/1 mol C₂) = 0

an architect is designing an overhang above a sliding glass door. during the heat of the summer, the architect wants the overhang to prevent the rays of the sun from striking the glass at noon

Answers

The overhang can only be 1/3 of the length of the beam, but it is more common to have a shorter overhang. This is the general rule.

How much excess overhang should a roof have?

If drip edge flashing is installed, the shingles' edge should hang over the roof between an inch and an inch and a half, or between a half-inch and three-quarters of an inch. If there is too much overhang, high winds could blow the shingles off; Too little water can allow water to seep into fascia boards or rakes.

How wide is the overhang?

The overhang on a typical countertop is typically 112 inches. Although some countertops have an overhang that is either longer or shorter, this is typically the standard length for overhangs in homes. Kitchen islands typically have an overhang of 12 inches, which is the standard length.

which problem can occur if your system case fan blows in the wrong direction?

Answers

The system overheat if a fan blows in the wrong direction, preventing airflow through the case.

In a computer case, how can airflow be controlled?

Air should follow a straight line through the case. In most cases, you want the case fans at the front of the case to draw in air and the ones at the back to blow out air. Because hot air will rise, vents at the top of your case should be used as exhaust fans.

What triggers CPU overheating?

Overheating of a computer is typically brought on by multiple factors. If dust is allowed to accumulate over time, it can obstruct the fans and overheat the CPU or GPU.

A manufacturer can sell product 1 at a profit of $2/unit and product 2 at a profit of $5/unit. Three units of raw material are needed to manufacture 1 unit of product 1, and 6 units of raw material are needed to manufacture 1 unit of product 2. A total of 120 units of raw material are available. If any of product 1 is produced, a setup cost of $10 is incurred, and if any of product 2 is produced, a setup cost of $20 is incurred. Formulate an IP to maximize profits.

Answers

The IP (Integer Programming) problem can be formulated as follows:

Maximize: 2x1 + 5x2

Subject to:

3x1 + 6x2 <= 120 (Constraint on the availability of raw materials)

x1, x2 >= 0 (Non-negativity constraint)

x1, x2 are integers (Integer constraint)

Where x1 is the number of units of product 1 produced, and x2 is the number of units of product 2 produced.

The objective function represents the profit earned by producing x1 units of product 1 and x2 units of product 2. The first constraint represents the availability of raw materials, which limits the production of the products based on the number of units of raw materials required. The non-negativity constraint ensures that the number of units produced is non-negative and the integer constraint ensures that the solution must be in integer.

What is the Integer Programming about?

In regards to the above, If any of product 1 is produced, a setup cost of $10 is incurred, and if any of product 2 is produced, a setup cost of $20 is incurred. The objective function can be adjusted to include these costs as follows:

Maximize: 2x1 + 5x2 - 10y1 - 20y2

Subject to:

3x1 + 6x2 <= 120 (Constraint on the availability of raw materials)

x1 - y1 = 0

x2 - y2 = 0

x1, x2, y1, y2 >= 0 (Non-negativity constraint)

x1, x2, y1, y2 are integers (Integer constraint)

Where y1 is a binary variable that indicates whether product 1 is produced (y1 = 1) or not (y1 = 0) and y2 is a binary variable that indicates whether product 2 is produced (y2 = 1) or not (y2 = 0). This constraints ensure that y1 and y2 are either 0 or 1.

1.4-8 a car weighing 130 kn when fully loaded is pulled slowly up a steep inclined track by a steel cable (see figure). the cable has an effective cross-sectional area of 490 mm2, and the angle a of the incline is 308. (a) calculate the tensile stress st in the cable. (b) if the allowable stress in the cable is 150 mpa, what is the maximum acceptable angle of the incline for a fully loaded car?

Answers

A steel cable is slowly pulled up a steeply inclining track by a car that weighs 130kN when fully loaded; (b) the maximum allowable incline angle is 30°.

What is a proper angle?

The maximum angle of incidence where the medium (typically air) meets the core (n1) is known as the acceptance angle () for an optical fibre. This angle determines how light enters and travels along the optical fibre. The optical fiber's numerical aperture is the sine of the acceptance angle.

The acceptance angle, which is calculated as the acceptance cone's half-angle, serves as a gauge of a fiber's capacity to gather light (the maximum cone of light that can enter or exit the fiber.) Be aware of what follows: The acceptance cone is triangular in shape.

The NA is related to the cutoff angle, which is the maximum acceptance angle (max) (Figure 1). At the intersection of the fiber's core and cladding, rays with an angle of incidence of maximum are totally internally reflected (TIR). These rays continue to be trapped in the core as they travel down the fibre.

Answers

What follows if the node is subjected to the forces Tension is present when the force is moving away from the node. It is a compression force if the force is moving in the direction of the node.

Which of the truss's members are under tension or compression based on the force in each one of them?

The method of joints involves calculating the force acting on each truss member while simultaneously including all forces acting at the joints in the equilibrium equation.

The secret to figuring out whether a diagonal or vertical member is in tension or compression is to see if they follow the same curve that a hanging chain would between the two end points.

The method of joints is a technique for figuring out the forces that are unknown to the members of a truss. The technique is usually the quickest and simplest way to solve for all the unknown forces in a truss structure because it centres on the joints or connection points between the members.

What are ROPS ?

On tractors and other agricultural machinery, rollover protection structures (ROPS) are metal bars (also known as rollbars), frames, or crush resistant cabs that are intended to provide an operator with a safe area in the event of a rollover or overturn1.

Roll bars or roll cages known as Rollover Protection Structures (ROPS) are made for agricultural tractors with wheels and tracks. When a rollover happens, ROPS are made to surround the operator in a protective zone. The purpose of ROPS is to stop the operator from being ejected out of the protected area.
