“Sprinklers are mechanical devices with nozzles used to distribute water by converting water pressure to a high-velocity discharge stream.”

“Sprinklers are intended to control fires, not necessarily to completely extinguish them. Therefore, some allowance is made for hose stream flows from hydrants or fire trucks when determining sprinkler system performance requirements. Sprinklers are usually laid out so that only a few need to be open to control a fire. Designs should not be based on the assumption that all sprinklers will operate simultaneously, unless there is reason to believe this is the case.”Reference: Bentley Systems Walski, Thomas M.
