determine the Sprinkler System Design Capacity in gallons per minute (GPM). Record this number in the GPM box below. B. Next, locate your system’s static pressure and move down that column and find the system’s working pressure; record it in the PSI box below. Working pressure will be used when choosing sprinkler heads and designing the system. Using the reciprocal of .433 or 1÷.433 = 2.31 we can determine that the potential head (h) by using the formula h = 2.31p where (p) is equal to pounds per square inch (psi). For ex- ample; if a gauge reads 43.3psi at the base of a water storage tank, multiplying 43.3psi x 2.31= 100 ft. The water column is 100 ft tall.
