Q. 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-2 and 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?
