Atwo-stage double acting air compressor, operating at 150 revolutions per minute, takes in air at 96.5 kpa and 27 c. the diameter of the lp cylinder is 36 cm, the stroke of both the lp cylinder and the hp cylinder is 38 cm and the clearance of both cylinders is 4%. the lp cylinder discharges air at 386.0 kpa which passes through an intercooler and enters the hp cylinder at 27 c and 370 kpa after which it is discharged from the hp compressor at a pressure of 1482 kpa. the polytropic coefficient in both cylinders n 1.3. atmospheric pressure and temperature are 101.325 kpa and 20 c respectively. disregarding the effect of the piston rods at the crank ends of the cylinders, determine (a) how much heat is rejected in the intercooler (b) the diameter of the hp cylinder and (c) the power required. to drive each of the compressors
