One of the steps in a typical refrigeration process is a boiler. Freon® 22 enters a steady-state boiler as a VLE mixture with a pressure P = 0.5 bar and quality of q = 0.2, and leaves the boiler as saturated vapor at P = 0.5 bar. Use the data in Appendix F to determine the following.

A. How much heat is added to the boiler per kilogram of entering Freon® 22.

B. The flow rate of Freon through the boiler if the rate of heat addition is Q = 200 kJymin.
