Evaporative cooling

This spring, tests were conducted in an evaporative-cooled wind tunnel facility to evaluate the effectiveness of different methods of wetting paper pads. The objective of these tests was to maximize cooling while minimizing water runoff. The temperature drop or cooling listed in the examples below is approximately the amount of cooling the different systems would produce on a warm summer day. The exact amount of cooling produced would change with weather conditions, pad area, etc. and thus the figures below should only be used for comparison purposes. These test results have been generally confirmed by field observations.
