How to calculate GPM (water flow) for a fire pump? …

The officer as well as the pump operator need to know the GPM flow from different nozzle tips to know how much fire each can extinguish. As a general rule, the maximum nozzle diameter should not exceed one-half of the size of the hose to which it is attached--for example, a2½-inch handline should not have a smooth bore nozzle any larger than1¼ inches.
