# How to Calculate Sprinkler Density

Save

Sprinkler density is a measurement of the volume of water that is released in a certain amount of time over a specific area. Being able to calculate sprinkler density is important in matters of safety, as a sprinkler system must be able to amply douse an area in order to help control a potential fire. You can find sprinkler density by performing a few simple equations.

### Things You'll Need

• Tape measure
• Sprinkler capacity (gallons per minute)
• Calculator (optional)
• Determine the square footage of the space in which the sprinklers will be installed. Do this by multiplying the length of the room by the width. For instance, if a room is 20 feet by 15 feet, it is 300 square feet.

• Make note of the number of gallons per minute that are released by a particular sprinkler system. You can call the sprinkler company to find out this information.

• Divide the number of gallons per minute by the square footage in order to determine density. For instance, if the sprinkler system within a 300-square-foot room releases 25 gallons of water per minute, perform the following equation: 25 / 300 = 0.083.
