Fifty (50) kmol per hour of air is compressed from P1 = 1.2 bar to P2 = 6.0 bar in a steady-flow compressor. Delivered mechanical power is 100.8 kW. Temperatures and velocities are: T1 = 300 K 411 = 10 m-s-1 T2 = 520 K 42 = 3.5 m-s-1 Estimate the rate of heat transfer from the compressor. Assume for air that Cp= (7/2)R and that enthalpy is independent of pressure. The rate of heat transfer from the compressor is -11.91 X kW
