C) Find the specific enthalpy of the refrigerant when it is a saturated liquid at 300 K. D) All of the work for the compressor is supplied by a Rankine heat engine that has an efficiency of 25%. Find the rate at which heat is removed from the condenser in this Rankine heat engine.

3. A steady state refrigerator operates on the vapor compression cycle. The refrigerant, in the vapor phase, behaves as an ideal gas with CP*=6R, and the specific enthalpy of the compound in saturated liquid and saturated vapor states at 270 K is given in the table below.

• The flow rate of the refrigerant is 100 mol/min.
• The vapor entering the compressor is saturated vapor at 270 K.
• The efficiency of the compressor is 75%.
• The liquid exiting the condenser is saturated liquid at 300 K.
• The mixture exiting the valve is 20% vapor and 80% liquid.
• There is no significant pressure change in either heat exchanger.
