Question:

Refrigerant-123, dichlorotrifluoroethane, which is currently under development as a potential replacement for environmentally hazardous refrigerants, undergoes an isothermal steady flow 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
R-123: M = 152.93, TC = 456.9 K, PC = 3.67 MPa
T1 = T2 = 40oC, x1 = 0
P2 = 100 kPa
