Question:
A single stage reciprocating air compressor has a swept volume of 2000 cm3 and runs at 800 rpm. It operates on a pressure ratio of 8 with a clearance 5% of the swept volume. Assume NTP room conditions at inlet (p = 101.3 kPa t = 15°C) and polytropic compression and expansion with n = 1.25 calculate i) Indicated power, ii) Volumetric efficiency, iii) Mass flow rate iv) Isothermal efficiency
