Answer: Air is compressed steadily by a compressor from
Chapter 7, Problem 7189(choose chapter or problem)
Air is compressed steadily by a compressor from 100 kPa and 208C to 1200 kPa and 3008C at a rate of 0.4 kg/s. The compressor is intentionally cooled by utilizing fins on the surface of the compressor and heat is lost from the compressor at a rate of 15 kW to the surroundings at 208C. Using constant specific heats at room temperature, determine (a) the power input to the compressor, (b) the isothermal efficiency, and (c) the entropy generation during this process.
