The whole idea is not to use this set up to gain data. It is to create a visual demonstration that can be used at trade shows and the like to illustrate the differences in fabric performance.
I am working on an air permeation experiment to show the difference in air permeation between three fabrics. If you use lab testing equipment, you get air perm values of 221 CFM, 86.6 CFM, and 35.6 CFM respectively. I tried a set-up with a ping pong ball in a clear tube and a fan blowing up on...
