Air is compressed at steady state from 100 kPa, 300 K, to 600 kPa, 440 K with a mass flow rate of 4 kg/s.

Heat transfer occurs at a rate of 42.3 kJ/kg of air flowing to cooling water circulating in a water jacket enclosing the compressor.

Neglect kinetic and potential energy changes, calculate the compressor power, in kW.
