Air is compressed at steady state from 1 bar, 300 K, to 6 bar with a mass flow rate of 4 kg/s. Each unit of mass passing from inlet to exit undergoes a process described by pv^1.27= constant. Heat transfer occurs to the cooling water circulating in a water jacket enclosing the compressor at a rate of 46.95 kJ per kg of air flowing. If kinetic and potential energy changes of the air from inlet to exit are negligible, calculate the compressor power.
