1 atm = 2116 lb/ft2 = 1.01 × 105 N/m2.
In the reservoir of a supersonic wind tunnel, the velocity is negligible, andthe temperature is 1000 K. The temperature at the nozzle exit is 600 K.Assuming adiabatic flow through the nozzle, calculate the velocity atthe exit.
Consider a converging nozzle with a low velocity at the inlet and sonic velocity at the exit plane. Now the nozzle exit diameter is reduced by half while the nozzle inlet temperature and pressure are maintained the same. The nozzle exit velocity will (a) remain the same (b) double (c) quadruple (d ) go down by half (e) go down by one-fourth
Air flows isentropically through a converging nozzle into a receiver where the absolute pressure is 240 kPa. Air enters the nozzle with negligible velocity, 406 kPa (abs.) of pressure, at a temperature of 95 oC. Determine the mass flow rate through the throat of this nozzle wich area is 0.01 m^2.
