A single acting, twin cylinder, Ammonia compressor with bore equal to stroke is driven by an engine at 250 rpm. The machine is installed in a chilling plant to produce 700 kW of refrigeration at -18°C evaporating temperature. At this temperature the cooling effect per kg mass is 1160 kJ. The specific volume of vapor entering the compressor is 0.592 m³ per kilogram. Assume 85% volumetric efficiency, determine the bore in mm. A. 400 mm С. 450 mm В. 300 mm D. 500 mm
