Air is compressed steadily by a compressor from 100 kPa and 20C to 1200 kPa and 300C

Question:

Air is compressed steadily by a compressor from 100 kPa and 20°C to 1200 kPa and 300°C 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 20°C. 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.
