# What is the flow rate of a fire sprinkler head?

**sprinkler heads**are designed to

**flow**between 10 and Page 3 13 gallons per minute. Generally, a

**fire**hose will

**flow**an average of 100 gallons per minute.

Similarly one may ask, what is the flow rate of a sprinkler head?

At different pressures, the **sprinkler head** and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home's water capacity was 10 GPM, you could place 3 **heads** per zone.

Additionally, how many gpm does a fire sprinkler head use? A **sprinkler system should** be designed so that water flow is at least 15 **gallons per minute** (**gpm**) and up to a maximum of 40 **gpm**. Regardless of the type, the standard requires that the water supply for a home **fire sprinkler system** accommodate one or two operating **sprinklers** for a period of seven to 10 minutes.

Also Know, how do you calculate fire sprinkler flow rate?

If, for instance, you have a **fire sprinkler** with a discharge coefficient of 6.2: 3.87 x 6.2 = 24 gallons per minute. Multiply this individual **flow rate** by the total number of **sprinklers**. If your system has, for instance, 15 **sprinklers**: 24 x 15 = 360 gallons per minute.

What is the K factor of a sprinkler head?

1.1. K-factor is a mathematical constant established by the sprinkler manufacturer that relates the flow of water that is discharged from the sprinkler at a given **pressure**.
