This is true but at a specified pressure (29.92in HG) and temp. so at a specified air pressure and temp the same CFM will always be the same mass of air. Similiar to Ohm's law.
That draws another question....whats the change in flow rate vs temperature? Will the heads flow more CFM at a higher temperature? If so will the extra flow come even close to making up for the lower mass due to the higher temperature?
I'd like to see comparisons of the CFM of the same head at different pressures and temperatures. I think the total change in VOLUME will be very little. Just a guess.
