Or, one can tape a big plastic garbage bag to the top of the amplifier and
time how long it takes to fill the bag with air. If a 20 cubic foot bag
fills
in 20 seconds then you have a flow of 60 cubic feet per minute. Should
agree
with the temperature calculations.
I think credit goes to G3SEK for this technique.
Wouldn't the flow actually be GREATER than 60 CFM because as the bag
inflated it would be ramping up the back pressure the fans would be working
into?
