Question: a compressor condenser throttling valve and evaporator are strung together...

Question details

A compressor, condenser, throttling valve, and evaporator are strung together to make a refrigeration system. The working fluid is R134a, with data at each state provided in the table below. The R134a mass flow rate is 2 kgs. Assume the heat transfer out of the condenser occurs at a temperature of 40degC.
