When supplying a sprinkler system, a 1000 GPM rated pumper should supply the FDC for every how many sprinklers estimated to be flowing?

A 1000 GPM rated pumper is capable of delivering a significant amount of water to a sprinkler system, which is crucial for effectively suppressing fires. The answer of 50 sprinklers is determined based on the water flow requirements of typical sprinkler systems.

Generally, each sprinkler head is designed to flow approximately 20 GPM when activated. Therefore, if you consider the total flow capacity of the pumper (1000 GPM), dividing this capacity by the flow rate of each sprinkler (20 GPM) leads to a total of 50 sprinklers that can be adequately supplied. This calculation is essential for ensuring that there is sufficient water pressure and supply when a fire occurs, allowing the sprinklers to function as intended to control and extinguish the fire.

Understanding this relationship between the flow rate of the pump and the demand of the sprinklers helps in effectively planning and implementing fire suppression strategies.
