Determine the amount of cfm flow required to provide as in put tp main pipe (branched out into perforated pipes)


Recommended Posts

Hi All,

 I have 3 pipes of 10" inches ID - 10 meter long (with 1" inch perforated holes at 0.2 m equi spaced)coneected to 30" main pipe ID. I wanted to calculate the amount of air (CFM)required to get 2m/s velocity outlet from each pipe. Any help would be highly appreciated.

Thanks so much in Advance.

I shan't give you the answer, as that is doing the job for you, but I will pont you in the right direction...(besides, there is sufficient ambiguity in your description to make this rather awkward without lots of clarification)

If you ignore compressability, model this as a "Constant Volume", you know the diameters of the pipes, and you also know how much total area the outlets are...the back-calculation is very simple from there! 

Good luck
