I found this the other night and I have seen alot of questions about flow size through size of pipe , baffles ect... Here is an example and a link to all of it. Alot of info to just post it.
Hope it might help some of you.
Pipe Sizing
It is important to size your overflow bulkheads and pipe correctly. Pipe that is too small will restrict flow, cause premature pump wear, and cause overflows to not run fast enough. Pipe that is too large will cause air bubbles and excess noise.
The chart below shows the flow rating you can expect from a stand pipe or drain of the given size. A U-tube of the same diameter will run slightly slower. Note that pipes can be paired up for increased flow (two 1" drains will carry a total 1200 gph). Try to select pipe that will carry slightly more than the expected flow rate.
Stand pipe Size Gravity Flow Rating
3/4" 330 gph
1" 600 gph
1 1/4" 910 gph
1 1/2" 1300 gph
1 3/4" 1800 gph
2" 2350 gph
2 1/4" 2960 gph
2 1/2" 3650 gph
2 3/4" 4450 gph
3" 5280 gph
