Consider a home dehumidifier, as shown in Fig. 11.5. Moist air at 78 F and relative humidity 85% enters at a volumetric flow rate of 330 ft³/min. The air exits at 92 F with a relative humidity of 50%, and the condensate exits at 52 F. Determine the electrical power supplied to the dehumidifier in kW, and determine the condensate flow rate in kg/s and gal/min. Assume that the dehumidifier is overall adiabatic and that the pressure is uniform at 100 kPa.
