72cf x 3 rotations per minute "ideally"
72cf x 3 =216cfm

ShOrTbUs said:thanks for the equation. technically im running less then the 217 right? because of the bends in the duct + its about a 20ft run of duct from start to end. but from the look of the numbers you posted, even with all that taking into account i'm prolly still geting at least 2 rotations per min. which is still sufficient right?
i run a oven range exhaust fan in the veg room. gotta use what we can get our hands on right bwd

I checked out your noise reducer DIY and am curious how you mounted the fan to the plywood? Was it screwed tight?
Really like your DIY posts, nice work
