WebRecommended fire flow durations¶ to be used in the four methods are given in Table 1-1. The maximum required fire flow for a single fire event is 12,000 gpm (757 L/sec). Insurance Services Office Method The ISO’s technique for calculating required fire flow is documented in its publication Fire Suppression Rating Schedule. The term used in ... WebGPM Formula - It is possible to determine water flow from any solid stream nozzle when the nozzle pressure and tip diameters are known. The following formula is used to determine the GPM flow of solid stream nozzles. GPM = 29.7·d²·√NP Where: GPM = discharge in gallons per minute 29.7 = a constant d = diameter of the tip measured in inches hudson\\u0027s outfitters and firearms
