Question 2 (50 points): The following figure shows a Refrigerant 22 vapor compression refrigeration system. A portion of the refrigerant leaving the condenser is diverted through an expansion valve to a secondary compressor. The evaporator capacity is 50 tons. Property values at several locations are given on the figure. State I has an enthalpy of 102.5 Btu/lb and entropy of 0.2334 Btu/Ib R, State 3 has a quality of O, state 7 has a quality of 1, and state 8 has an enthalpy of 118.64 Btu/lbm. Clearly state all assumptions and calculate: the mass flow rate at the inlet to each compressor (lb/min) 1)_ 2).
