1. A compressor has a piston diameter of 500 mm and a stroke length of 600 mm.If the clearance volume is 0.01 m3, the inlet pressure is 100 kN m-2, the delivery pressure is 500 kN m-2and the index of compression is 1.3, calculate:

(a)The volumetric efficiency of the compressor

(b)If the pressure ratio is doubled, what will the new clearance volume need to be in order that the volumetric efficiency is not reduced?
