Air (an ideal gas) enters a compressor with a pressure of 14.4 psia, a temperature of 70F, and a volumetric flow rate of 50 ft/s. The air exits to 70 psia, 190F. If the measured power required by the compressor is 250 hp, calculate the heat transfer rate from the compressor to the surroundings, in Btu/h. Ignore changes in kinetic and potential energy. Assume variable specific heats. Air (an ideal gas) enters a compressor with a pressure of 14.4 psia, a temperature of 70F, and a volumetric flow rate of 50 ft/s. The air exits to 70 psia, 190F.
