Consider a reciprocating air compressor with 3-stage, 7.2 m3/min free air delivery at atmospheric conditions of 144 kPa and 26 0C, respectively. The polytropic compression index is 1.34, while the delivery pressure is 1,665 kPa. The mechanical and motor-drive efficiencies are 85% and 93%, respectively. Accept complete inter-cooling and neglect clearance volumes. If the specific heat capacity of air at constant pressure and volume are 1.006 kJ/kg K and 0.716 kJ/kg K, respectively. Calculate the rate of heat rejected in the intercooler in kilowatt to 1 decimal place.
