I come up with 1,737 usgpm.
RE: 12 psi pitot through 4.5" Pumper Outlet
I came up with the same thing and was curious as to why they differed so.
RE: 12 psi pitot through 4.5" Pumper Outlet
Apply pumper modifier: 1883*0.83 = 1563 GPM.
It seems they are right on. Probably just rounding differences.
Don't forget that per 291, you have to do the pumper modifier to the flow test data you get.
