Moist air at 25 °C and 50% relative humidity enters a dehumidifier operating at steady state with a volumetric flow rate of 280 m/min. The moist air passes over a cooling coil and water vapor condenses. Condensate exits the dehumidifier saturated at 10°C. Saturated moist air exits in a separate stream at the same temperature. There is no significant loss of energy by heat transfer to the surroundings and pressure remains constant at 1.013 bar. Determine (a) The mass flow rate of the dry air, in kg/min.
