Air enters a compressor operating at steady state at 1 bar, 20 C with a volumetric flow rate of 9 m3 /min and exits at 5 bar, 160 C. Cooling water is circulated through a water jacket enclosing the compressor at a rate of 8.6 kg/min, entering at 17 C, and exiting at 25 C with a negligible change in pressure. There is no significant heat transfer from the outer surface of the water jacket, and all kinetic and potential effects are negligible. For the water-jacketed compressor as the control volume, determine the power required, in kW, and the rate of entropy production, in kW/K.
