What is the flow rate (GPM) of a typical sprinkler head?

The flow rate of a typical sprinkler head is about 15 gallons per minute (GPM). This number is commonly used because it strikes a balance between providing sufficient water volume to effectively suppress or control a fire while also minimizing water waste and potential damage to the structure. Depending on the type and design of the sprinkler system, as well as the specific application and fire risk, flow rates can vary, but 15 GPM is a standard figure in many fire protection scenarios.

Understanding these flow rates is critical for fire department operations, particularly in planning appropriate water supply during firefighting efforts and ensuring that sprinkler systems are designed to meet the water demands of a building. Firefighters must be familiar with these values to assess the effectiveness of a sprinkler system quickly and plan their strategies accordingly.
