Extracted text: 10. Catalog data for a six-cylinder refrigerant 22 compressor operating at 29 rls indicate a refrigerating capacity of 96.4 kW and a power requirement of 28.9 kW at an evaporating temperature of 5°C and condensing temperature of 50 °C. The performance data are based on 3 °C liquid subcooling and 8 °C superheating of the suction gas entering the compressor. The cylinder bore is 67 mm and the piston stroke is 57 mm. Compute (a) the clearance volumetric efficiency if the clearance volume is 4.8 percent, (b) the actual volumetric efficiency and (c) the compression efficiency.
