150 psi 500 1 1/2” 1 x 50 ft 58. ... GPM = 29.83 x 0.99 x 2” squared x square root of 72psi. GPM = 29.83 x 0.99 x 4 x 8.485 = 1002 gpm. GPM = 1002. If you do not want to use the formula above see Table B, which gives the nozzle pressure for smooth bore nozzles. Discharge Table for Smooth Nozzles ................
