Moist air steadily enters a room at 20° C and 1 atm with a dew-point temperature of 7°C at a rate of 15m³/min. As the moist air passes through the room it is heated at a rate of 7kW by a source at 65° C. Liquid water at 20° C is also supplied to the room at a rate of 5 kg/hr and is evaporated into the moist air. Determine the temperature (°C) and relative humidity of the moist air as it leaves the room.
