flows through a nozzle which has inlet areas of (10 cm ^ 2) . If the air has a velocity of (120 m/s) a temperature (300K) and a pressure of (700kpaat the inlet section and a pressure of 250kpa) at the exit find the mass flow rate through the nozzle and the velocity at the exit of the nozzle, assuming one dimensional isentropic flow. (R=287 J/kg. K), (K=1.4).
