A single stage, single acting air compressor running at 1500 rpm delivers air at 28 bar. For this purpose the induction and free air conditions can be taken as 1.013 bar and 20 Degree Celsius, and the free air delivery as 0.29 cubic meter per minute. The clearance volume is 4% of the swept volume and the stroke/bore ratio is 1.3/1. Take the index of compression and re-expansion as 1.3. Calculate a. The bore and stroke b. The volumetric efficiency c. The indicated power d. The isothermal efficiency
