A refrigeration system using R-12 is to have a refrigerating capacity of 60 kW. The evaporating temperature is 10°C and the condensing temperature is 42°C. Determine (a) the volume flow rate of refrigerant at inlet to the compressor, (b) the power required by the compressor, and (c) the fraction of vapor mixture at entrance to the evaporator expressed both on a mass basis and volume basis.
