Moist air at 15°C, 1.3 atm, 63% relative humidity, and a volumetric flow rate of 770 m3/h enters a control volume at steady state and flows along a surface maintained at 187°C through which heat transfer occurs. Liquid water at 15°C is injected at a rate of 7 kg/h and evaporates into the flowing stream. For the control volume, cv = 0, and kinetic and potential energy effects are negligible. If moist air exits at 45°C, 1.3 atm, determine: the rate of heat transfer, in kW. the rate of entropy production, in kW/K.
