Never thought of it in that context before, thanks.

I always thought that high velocity air flowing through a restriction was cooler after the restriction. I also look at the atmosphere as a column of air that extends from sea level to the edge of space, that weighs a nominal 14.7 pounds, and is trying to fill any void due to mass and gravity.
I know that the grilles on buildings in the middle east serve as a form of passive cooling of the air as it passes through those grilles.
Bottom line for me is the Mercedes SB that claimed 7%. I never studied engineering in any formal classroom scenario, I did consider Physics for a short time, but ended up as an apprentice in a body shop at just past 18, and maxed out my Social Security contribution barely 4 years later. Pop could not afford to finance the education of his 4 sons. Today he is closing in on 91and can easily finance the education of his grandsons, if that is what they want.
