As shown in Fig. P12.51, moist air at 308C, 2 bar, and 50%

As shown in Fig. P12.51, moist air at 308C, 2 bar, and 50% relative humidity enters a heat exchanger operating at steady state with a mass flow rate of 600 kg/h and is cooled at constant pressure to 208C. Ignoring kinetic and potential energy effects, determine the rate of heat transfer from the moist air stream, in kJ/h.
