Thanks guys. Those numbers are close enough for me to have made my point in a discussion... the point being that 10 times the diameter is NOT 10 times the flow... :-) ......especially when we already know that double the diameter is 4x the flow...
If I have water being pumped through two lengths of pipe, both at 50 psi, but one pipe is 1.25" diameter and the other is 10" diameter, approimately how many gpm will be flowing through each pipe? Thanks in advance!
