A two stage reciprocating air compressor works between pressure limits of 1 bar and 20 bar. The inlet temperature is 150C and the polytrophic index is 1.29. Inter cooling between stages reduce the air temperature back to 150C. Both stages have the same stroke. Neglect the effect of clearance volume.
Calculate the following:
a) The free air delivery for each kWh of indicated work.
b) The mass of air that can be compressed for each kW h for indicated work.
c) The ratio of the cylinder diameters
