A 15hp motor is used to drive an air compressor. The mechanical and compressor efficiency are 65% & 70% respectively. Find the mass of air needed per minute, power loss at the shaft and power loss at the compressor, if air is available at 30C. The pressure compresses to 6 times its original pressure.
