Air at 100 kPa and 225 K is compressed steadily (in a compressor) to 575 kPa and 425 K. The mass flow rate of air through the compressor is 0.05 kg/s. A heat loss of 15 kJ/kg occurs during the process. Assume changes in kinetic and potential energies are negligible. Determine the necessary power in kW required to drive the compressor.
