An air compressor, as shown in the figure, compresses air from atmospheric pressure (100 kPa) and temperature of 280 K to a discharge condition at a pressure and temperature of 600 kPa and 400 K, respectively. The mass flow rate of the air entering the compressor is 1 kg/s. The compressor losses heat through its walls at a rate of 40% of the total required power running the compressor. Assume that the changes in both kinetic and potential energies are negligible. The absolute value of the power consumed by the compressor is ...kW?
