how to do the mechanical design of gas liquid ( flash) separator??
what are the equations used for its mechanical design???

Nitrogen is stored in a large chamber under conditions of 450 K and 1.5x10^5 N/m^2. The gas leaves the chamber through a converging-only nozzle whose outlet area is 30 cm^2. The ambient room pressure is 1x10^5 N/m^2 and there are no losses.

a) What is the velocity of the nitrogen at the nozzle exit?

b) What is the mass flow rate?

c) What is the maximum flow rate that could be obtained by lowering the ambientpressure?

A six-cylinder engine uses pushrods to actuate the valves. The pushrods are 8.0 mm in diameter and are 650 mm long. Suppose the temperature can change from -40^oC to 116 ^oC. If the pushrods are allowed to expand unrestrained, calculate the change in length in mm to two decimal places. Assume they are made from AISI 1040 steel, E = 207 GPa, and have a coefficient of thermal expansion of 11.3 x 10^-6/^oC.

If the pushrods were installed with zero clearance between the parts when at 25^oC, Find the clearance in mm to three decimal points between the parts when the temperature is at -40^oC.

If the pushrods were installed with zero clearance between the parts when at 25^oC, Find the clearance between the parts when the temperature is at -40^oC.

Find the stress in MPa in the rod if the temperature rises to 116^oC.

An air-conditioned zone is at 72°F and 40% relative humidity. The total heating load of the space is 300,000 Btu/hr, out of which 60,000 Btu/hr is latent heating load. To maintain an appropriate indoor air quality 1000 CFM of outdoor air at 30°F and 80% relative humidity is required. Determine:

a) flow rate of supplied air at 25 °F above the zone temperature

b) total heating unit load

c) amount of water required for the humidifier

Please show diagrams in psychometric chart too!! Thank you.

Plot several streamlines (including the stagnation and a few internal and external streamlines) of a 2-D semi-infinite body in a free stream of U = 0.35 m/s, and the asymptotic radius of 50 cm.​

Use MATLAB for plotting and calculations.

- Include the body geometry (stagnation streamline) and choose appropriate streamlines to represent the flow around the objects.

- Include a brief explanation and relevant formulas.

Is the relation "delta h(enthalpy) = m * Cp,avg * delta T" restricted to constant pressure process only, or can it be used for any kind of process of an ideal gas? detailed and easy-to-understand reason included, please.

a MATLAB script that: • Prompts the user for - a lower-bound for the plot interval and stores it in a variable named Lbound - an upper-bound for the plot interval and stores it in a variable named Ubound, and - the number of points at which a function is to be evaluated to generate a plot of the function over the specified range and stores it in a variable named npoints. • Generates a plot of f(x) = x3 - 3x2 – x + 3 over the specified range using the specified number of points. The plot title should be “f(x) = x^3 - 3x^2 – x + 3”, the axis labeled “x”, and the y-axis labeled f(x). NOTE: There should not be any display of information to the CW. Suggestion: You should be able see the interesting portion of this function if you plot on -1.5 ≤ x ≤ 3.5.

An expansion valve in a refrigeration cycle throttles R134a from 1.2MPa saturated liquid to 0.32MPa. What is the specific volume at the exit of the expansion valve in unit of m3/kg. Round the result to 4 decimal places.

Design a speed-increasing gear train with a speed ratio of SPR defined below:

Speed ration = 13

The gear train does not need to be reverted. Specify the appropriate numbers of teeth to minimize the gearbox size while avoiding the interference problem in the teeth. Perform the analysis subject to the following constraints:

A) Use a 20° pressure angle and match SPR exactly.

B) Use a 25° pressure angle and match SPR exactly.

C) Use a 20° pressure angle and for a speed ratio within 1% of SPR.
