Determine the constants A and B in a Classius-Claperon type equation for estimating vapor pressures of this VOC. Use the equation to estimate the vapor pressure of the VOC at 77.0 deg F. Ans. 0.55 psia.

Q1. Explain how (EinScan-SE?) 3D Scanner work ?

Which of the following statements about a real Rankine cycle is true?

Top of Form

(A)

The entropy of the working fluid increases across every component.

(B)

The temperature of the working fluid increases across the pump.

(C)

The pressure of the working fluid increases across the boiler.

(D)

The work performed by the pump is equal to the product of the power into the pump and the pump efficiency.

An air-standard Carnot cycle is executed in a closed system between the temperature limits of 350 and 1200 K. The pressures before and after the isothermal compression are 150 and 300 kPa, respectively. If the net work output per cycle is 0.5 kJ, determine (a) the maximum pressure in the cycle, (b) the heat transfer to air, and (c) the mass of air. Assume variable specific heats for air.

A certain engine develops an output torque of 1800 + 200sin2?? Nm, where ? is the crank angle measured from some datum. This engine drives a machine which requires a driving torque of 1800 + 300sin?? Nm. The rotating parts have a mass of 100 kg, with a radius of gyration of 0.25 m. The maximum speed of the rotating parts is observed to be 250 rev/min. a) Sketch both the driving and load torque curves on the same axes b) Prove that during 1 cycle, the maximum energy is stored between ? and 5.56 radians c) Determine the maximum energy stored d) Determine the minimum speed of the rotating parts e) Determine the coefficient of fluctuation of speed f) Determine the mean power developed by the engine

1a. The latitude in Ames Iowa is 42 degrees. Most outside walls on homes are 10 feet high. As an energy conscious building designer, you would like the wall overhang to shade 90 percent of the wall at the summer solstice. Perform an analysis/design to determine the length of the overhang. show all work and discussion

1b. The latitude of UH is 30.6 degree (remember at the noon equinox solar angle from the vertical is 30.6 degree) Determine the degree above the horizon the sun sits at noon on the winter solstice. Repeat for the summer solstice. use sketches to perform and illustrate calculations

Compare and contrast response (how material behaves/responds when subjected to a load) and failure (where the material fails or the parts are damaged) properties and give three examples of each.

. A 20 mm diameter sphere made of aluminum alloy 2024 initially at a uniform temperature of 500 ºC is suddenly immersed in a saturated water bath maintained at atmospheric pressure. The surface of the sphere has an emissivity or 0.25. Determine.

a.) the total heat transfer coefficient for this initial condition, and

b.) what fraction of the total coefficient is contributed by radiation. (~180 W/m2 -K, ~ 7%)

Water vapor enters a subsonic diffuser at 0.5 bar,
175 °C, and 200 m/s. The diffuser inlet is 100 cm2. During passage through the diffuser, the fluid velocity is reduced to 50 m/s, pressure increases to 1.0 bar and heat transfer to the surroundings is

0.5 kg/kJ. Determine

a) the final temperature,

b) the mass flow rate [kg/s] and

c) the outlet area [cm2]

For a catapult project I must make a MATLAB code that should make use of the projectile motion

equations so for a given input range R (horizontal distance from the catapult to the target), the code

outputs the necessary velocity and firing angle of the catapult. What is the code for this? I am lost.

Fix the bugs in this matlab program so that it solves.
