An air-standard Brayton cycle is utilized as a jet propulsion engine. The aircraft flies at an altitude of 5000 m at a constant speed of 260 m/s. The cycle operates with the following conditions: diffuse inlet: 60 kPa, 250 K; turbine inlet, 1300 K; pressure ratio, 8:1; air mass flow, 60 kg/s; all components are ideal. Find the compressor power, the temperatures and pressures throughout the cycle, and the exit-jet velocity.
