Air is compressed in an axial-flow compressor operating at steady state from 27°C, 1 bar to a pressure of 2.1 bar. The work required is 94.6 kJ per kg of air flowing. Heat transfer from the compressor occurs at an average surface temperature of 40°C at the rate of 14 kJ per kg of air flowing. The effects of motion and gravity can be ignored. Let T0 5 20°C, p0 5 1 bar. Assuming ideal gas behavior, determine (a) the temperature of the air at the exit, in °C, and (b) the rate of exergy destruction within the compressor, in kJ per kg of air flowing.
