Figure 1 illustrates the amount of water which will evaporate from properly wetted, 15 cm paper evaporative cooling pad system, as a function of outside temperature and relative humidity. The amount of water evaporated is provided in terms of gallons per minute per 100,000 cmh of operating tunnel fan capacity. For example, if a house had 100,000 cmh of tunnel fan capacity and the outside temperatu ...
