Question:
Air at30°C and 2 MPa flows at steady state in a horizontal pipeline with a velocity of 25m/s . It passes through a throttle valve where the pressure is reduced to 0.3 MPa . The pipe is the same diameter upstream and down stream of the valve.
What is the outlet temperature and velocity of the gas?
Assume air is an ideal gas with a temperature independent Cp=7R2 and the average molecular weight of air is 28.8.
