Question: Consider an ideal air-standard cycle for a gas-turbine, jet propulsion unit, such as that. The pressure and temperature entering the compressor are 90 kPa, 290

Consider an ideal air-standard cycle for a gas-turbine, jet propulsion unit, such as that. The pressure and temperature entering the compressor are 90 kPa, 290 K. The pressure ratio across the compressor is 14 to 1, and the turbine inlet temperature is 1500 K. When the air leaves the turbine, it enters the nozzle and expands to 90 kPa. Determine the pressure at the nozzle inlet and the velocity of the air leaving the nozzle.
