I am looking for the ASTM B117 standard. It would be great if there is a web site to download these standards. It would even be better if it was free!
Thank you
In a direct evaporative cooler how much water does it take to drop 1 cubic foot of 90 degree F 50% Rh air to 70 degree F?
A simple spreadsheet or software to calculate water consumption in evaporative coolers would be helpful.
Thanks
