A single acting two-stage air compressor deals with 4 m^3/min of air under atmospheric conditions of 1.013 bar and 15°C with aspced of 250r.p.m. The delivery pressure is 80 bar. Assuming complete inlercooling, find the minimum power required by the compressor and the bore and stroke of the compressor. Assume a piston speed of 3 m/s, mechanical efficiency of 75 percent, and volumetric efficiency of 80 percent per stage. Assume the polytropic index of compression in both the stages to be it = 1.25 and neglect clearance.
