A single-acting air compressor has a clearance volume of 10%. Air is received at 90 kPa and 293 K and is discharged at 600 kPa. The compression and re-expansion curve are polytropic with n = 1.28. The pressure drops are 5 kPa and 10 kPa at the suction and discharge ports, respectively. The compressor piston displacement is 490 cm3 when operating at 900 rpm. Determine the mass of air compressed in kg/hr.
