A compressor used to deliver 2.10 kg/min of high pressure air requires 8.087 kW to operate. At the compressor inlet, the air is at 100 kPa and 26.85 degrees Celsius. The air exits the compressor at 529 kPa and 256.85 degrees Celsius. Heat transfer to the surroundings occurs where the outer surface (boundary) temperature is at 345.1 degrees Celsius. Determine the rate of entropy production (kW/K) within the compressor if the air is modeled as an ideal gas with variable specific heats.
