A turbojet aircraft flies at 575 mph at an altitude of 16,500 ft, where Pa = 8.7 psia and Ta = 460 R. The compressor pressure ratio is 8, and the maximum temperature at the combustion chamber is 1840 degrees Farenheight. Assuming ideal performance of the various components of the engine, determine the compressor-work input, the pressure and temperatures throughout the cycle, and the exit-jet velocity.
