Question:
An airplane flies at a speed of kmh at an altitude where the pressure conditions are kPa and the temperature is deg C The turbine compressor has pressures of and the temperature at the turbine inlet is deg C All processes are isentropic air can be considered an ideal gas. At the inlet before the compressor there is a diffuser and at the outlet of the engine a nozzle.
Calculate the following
The pressure at the compressor inlet and at the turbine outlet for variable specific heats
Exhaust velocity and propulsive efficiency
The pressure at the inlet of the compressor and at the outlet of the turbine and constant specific heats
The exhaust velocity at the exit nozzle for constant specific heats
