A single stage double acting air compressor handles 17 m3 of air per minute, measured at 1 bar and 15oC. The pressure and temperature at the end of suction are 0.98 bar and 32°C. The air is delivered at 6.325 bar. Assuming a clearance factor of 5% and the compression and expansion processes to follow the polytropic law pVl.32 = constant, determine the stroke volume of the compressor running at 500 r.p.m, Also calculate the indicated power in kW of the compressor. R=287 J/kgK. Neglect the effect of piston rod.
