We installed a whole house fan, and we love it. Here is my observation. I close all the windows besides our family room slider, which I open all the way. I turn on the whole house fan. I feel the flow of air at the exit point of the room. I then close it, 1/4, 1/3, 1/2, 2/3, 3/4, 7/8.

The feel of the air goig past me at the exit of the room feels significantly greater at 2/3 than the other points. I figure there has to be an optimal point, but not sure the dynamics that would cause an optimal point. Can anyone explain?
