Air is compressed in a two-stage, double acting acting compressor which is electrically driven at 165 rpm. The low pressure cylinder (30.5 x 35.5 cm) receives 6.85 m3/min of air at 96.53 kPaa, 43.3 C, and the high-pressure cylinder (20.3 x 35.5-cm) discharges the air at 717.06 kPaa. Piston rods are 5.1 cm in diameter and the isothermal overall efficiency is 74%. Find a. The volumetric efficiency, % b. The power of the driving motor, kW c. The power savings for two-stage compressor, kW
