Question
Q.2. Air flows through a constant-area duct is connected to a reservoir at a
temperature of 500°C and a pressure of 500 kPa by a converging nozzle, as shown
in Figure. Heat is lost at the rate of 250 kJ /kg. Determine the exit pressure and Mach
number and the mass flow rate for a back pressure of 0 kPa.
q = 250 kJ/kg
Pr = 500 kPa
Tr = 500°C
Po = 0 kPa
D= 0.02m
