Moist air at 40 oc and 60% relative humidity enters a dehumidifier operating at stead state witha volumetric flow rate of 280 m3/min. the moist air passes over a cooling coil and water vapor condenses. condensate exits the humidifier saturated at 20 oc. 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, (b) the rate at which water is condensed, in kg per kg of dry air flowing through the control volume, (c) using the psychrometric chart, determine the wet-bulb temperature of the moist air entering the dehumidifier, in oc.
