25. creases through the day can be affected by local weather systems and proximity to large bodies of water If an increase in temperature accompanied by a weather system containing moisture moves in then the drop in humidity will not oe as great Nevertheless the fact remains that relative humidity does drop as air temperature increases In fact for every 90 F rise in temperature the moisture holding ability of air doubles For instance if the temperature of the air was 70 F and the relative humidity was 100 at 5 a m and the temperature increased to 90 F at noon the moisture holding ability of the air would double As a result the air would now be holding only half of the moisture it is capable of holding and the relative humidity of the air would drop to 5096 The hotter the day the drier the air becomes and the more cooling that can take place through the evapo ration of water This means that when the day gets hot enough to require cooling the relative humidity will be much lower than in the morning and will allow an evaporative cooling device to work more effectively Since any evaporative cooling device must evaporate water to achieve cooling more water vapor is put into the air As the ambient relative humidity increases it becomes more difficult to put moisture into the air The efficiency of any evaporative cooling device is directly related to its ability to evaporate water cooling the air at a given relative humidity A unit wit
