Consider an air-standard cycle for the turbojet power plant shown in Fig. 8.13. The temperature and pressure of the air entering the compressor are 1 bar and 303.15 K (30°C). The pressure ratio in the compressor is 6.5, and the temperature at the turbine inlet is 1373.15 K (1 100°C). If expansion in the nozzle is isentropic and if the nozzle exhausts at 1 bar, what is the pressure at the nozzle inlet (turbine exhaust) and what is the velocity of the air leaving the nozzle?
