How to Calculate GPM From PSI | Hunker

Interpolating between 35 GPM and 40 GPM, the pressure loss computes to a value between 0.9 and 1.2 PSI loss per 100 feet of pipe. Since 37.5 GPM is halfway between the two flow readings of 35 and 40 GPM, the interpolation will work out to about 0.707 of the way between 0.9 and 1.2 PSI loss (again the square function). So the loss would be:
