Air at 5 bar and 560K is expanded in steady flow in a horizontal convergent–divergent duct to an exit velocity
of 640 ms−1. The walls of the duct are heated so as to keep the temperature drop to one-half the value of an
isentropic expansion to the same velocity and pressure from the same initial conditions. Calculate, assuming
negligible initial velocity:
a. the heat supplied;
b. the final temperature;
c. the mass flow rate per square metre of exit area.

Air is supplied to a convergent–divergent nozzle from a reservoir where the pressure is 100 kPa. The air is then discharged through a short pipe into another reservoir where the pressure can be varied. The cross-sectional area of the pipe is twice the area of the throat of the nozzle. Friction and heat transfer may be neglected throughout the flow. If the discharge pipe has constant cross-sectional area, determine the range of static pressure in the pipe for which a...
