One of the steps in a typical refrigeration process is a condenser. Freon® 22 enters a condenser at steady state as superheated vapor at P = 3 bar and T = 30°C. It leaves the condenser as saturated liquid at P = 3 bar. Use the data in Appendix F for the following.

A. Find the heat removed from the condenser, per kilogram of entering Freon.

B. Find the flow rate of Freon in the condenser, if the rate at which heat is expelled from the condenser is Q = 250 kJ/min.

C. Determine the change in entropy of the universe resulting from the process in part B, assuming the coolant used for the condenser is a heat reservoir at a temperature 5°C lower than the temperature of the Freon exiting the condenser.
