Air is compressed in an axial-flow compressor operating at steady state from 27°C, 1 bar to a pressure of 2.1 bar7.60The work required is 94.6 kJ per kg of air flowing. Heat transfer from the compressor occurs at an average surfacetemperature of 40°C at the rate of 14 kJ per kg of air flowing. The effects of motion and gravity can be ignored. Let To =20°C, Po 1 bar. Assuming ideal gas behavior, (a) determine the temperature of the air at the exit, in °C, (b) determine therate of exergy destruction within the compressor, in kJ per kg of air flowing, and (c) perform a full exergy accounting, in kJper kg of air flowing, based on work input
