Poblem Comergini sentropie regim (no shock waves) Consider isentropic flow through a converging-diverging nozzle. The exit area of the nozzle is , and the throat area of the nozzle is . The air entering the nozzle has stagnation conditions: , and Use Figure D.1 or Table D (a) Calculate the mass flow rate for choked flow (that is, sonic flow at the throat). Hints: See Section 11.7, use Figure D.1 to find density and temperature at M 1 (throat), find...

Consider a converging-diverging nozzle with subsonic inlet conditions. Answer with justification. Use the sketch of the pressure diagram wherever appropriate. Gamma = 1.4. R = 286.9 J/kg-K It is given that when the exit pressure is 1MPa, a certain nozzle is operating under choked, subsonic and isentropic conditions. The mass flow rate is found to be 1000 kg/s. What will be the mass flow rate if the exit pressure is 100 kPa? Explain.

Air flows through a converging-diverging nozzle/diffuser. Assuming isentropic flow, air as an ideal gas, and constant specific heats determine the state at several locations in the system.
