The formula I have is; Q=29.83*cd2*sqrt of pitot pressure.

Please let me know. If you flow a 2 1/2" hydrant, and the pitot reading is 55 psi the gpm will always be 1250. Right? (I understand you factor in the coefficient of the hydrant nozzle). My pitot gauge manufac tured by Potter shows BOTH gpm AND psi. I'm looking at a flow test paper. Through a 2.5" hydrant outlet. Residual is 90 psi @ 840 GPM. Is this possible?
