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.
