CNC-Dude:
Thanks for the response. My gut was telling me about the same thing. Did you come to this by years of experience or did you have some reference material at your disposal?
I've been trying to come up with a (relatively) simple computation that will get me in the ball park for any given cylinder size and RPM range. So far, I'm missing something because the answers I get are either nowhere near enough or way too much flow. Probably some dumb computational error when converting units of measure (either time or volumn).
But at least you have confirmed a target CFM range so I will make another stab at a formula, knowing approximately the answer it should provide.
Thanks again.
Russ
