35% Air (udara) is compressed in an axial flow compressor operating at steady state from 27°C, 1 bar to a pressure of 4,41 bar. The work input required is 96,23 kJ/kg of air flowing through the compressor. Heat transfer from the compressor occurs at the rate of 15,65 kJ/kg at the surface of the compressor where the temperature is 40'C. Kinetic and potential energy changes can be ignored. Assuming air as an ideal gas with constant specific heat, cp =...
