Question:

Refrigerant-123, dichlorodifluoromethane, which is currently under development as a potential replacement for environmentally hazardous refrigerants, undergoes an isothermal SSSF process in which the R-123 enters a heat exchanger as saturated liquid at 40C and exits at 100 kPa. Calculate the heat transfer per kilogram of R- 123, using the generalized charts, Fig. D.2
