Does anyone know a formula to calculate what CFM that is needed for an Audio Visual Rack?

Question

I am trying to come up with a formula to figure out exactly how much Cubic Feet per Minute that I need to remove from an AV Rack or credenza. Anyone have any ideas? I tried using the middle atlantic calculators, but if you plug the same numbers into both there calculators you get completely different numbers on the output side.

Answer 1

The best solution is to allow free convection to cool the stack. It requires that free airflow be allowed to rise around the stack without obstruction.
