FPM to CFM
I need to measure the amount of cfm in a 24" pipe, I can calculate the FPM but how can I convert to CFM.

Re: FPM to CFM
You need to multiply the feet per minute times the crosssectional area of the pipe.
Make sure all units are the same base unit. feet/minute * square feet = cubic feet/minute The formula for the area of a circle is Pi*radius˛, with radius being 1/2 the diameter. Is the 24" the inside diameter? If so then: 3.14 * (1 foot * 1 foot) = 3.14 square feet FPM * 3.14 square feet = CFM

Re: FPM to CFM
I need to know 500 FPM = how much CFM

Re: FPM to CFM
That depends on the crosssectional area of the pipe. (or river or whatever it is)
feet/minute (FPM) * square feet = cubic feet/minute (CFM)

Re: FPM to CFM
How do you calculate the cross sectional?

#6




Re: FPM to CFM
The formula for the crosssectional area of a pipe is:
Area = Pi * radius^{2}
