Moist air at and 50% relative humidity enters a dehumidifier operating at steady state with a volumetric flow rate of . The moist air passes over a cooling coil and water vapor condenses. Condensate exits the dehumidifier saturated at . 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, (20 points) (b) the rate at which water is condensed in kg of condensed water per kg of dry air.
