In hot, dry climates an inexpensive alternative to air conditioning is the swamp cooler. In this device water continuously wets porous pads through which fans blow the hot air. The air is cooled as the water evaporates. How much water must be evaporated to cool the air in a room of dimensions 4.0 m x 5.0 m x 3.0 m by 20. C? Assume that the enthalpy of vaporization of water is the same as it is at 25 c.
