A constant-area circular duct connected to a C-D nozzle with A = 30cm and A = A = 72cm. The nozzle is fed by a large compress-air tank with pressure of 1000 kPa and temperature of 500 K. The flow is shockless everywhere and is supersonic at the nozzle exit the duct at a rate of 50 kJ/(kg of air). Assuming frictionless flow and ideal gas. Between section 1 and 2, heat added to (a) (3 points) Draw the T-S diagram of the flow; (b) (2 points) Calculate the flow rate, m; (c) (5 points) Calculate M, P2, T2, Poz. Po= 1000kPa To = 500K 1, nozzle exit t, nozzle throat for 8Q dm = 50 kJ/kg 2 Find: M, P2, T and Poz
