The engineering Question today is:
What is the max flow rate one could expect through a 3" pipe from a bottom drain? (When the 3" pipe is used for the intake of a pump)
My engineering book states that a 3" pipe max flow rate is 9,000 gph or 150 gpm
(No PSI is mentioned - so we will base the response on what our typical pond pump will "pull through" a 3 inch pipe...
Is this true? Or does someone else have a more precise engineered response..
