The clearance volume of a single cylinder air compressor is 10% of the swept volume. The compressor has a bore of 120mm and a stroke of 152 mm and runs at 400mm. Suction conditions are 1 bar and 24°C and the delivery pressure is 10 bar. Compression and re-expansion curves follow the law PV1.3 = constant. Calculate the diagram volumetric efficiency, the rate of air delivery, and the power input required to drive the compressor assuming a mechanical efficiency of 74%. Take R = 0.287 kJ/kgK.
