What flow rate is typically expected from a sprinkler head covering 100 sqft?

The flow rate of a sprinkler head is influenced by various factors, including the type and design of the sprinkler system, as well as the coverage area. For a typical sprinkler head covering an area of approximately 100 square feet, a flow rate of 20 gallons per minute (gpm) is expected as it is a common standard based on system performance and necessary water application rates for effective fire suppression.

This flow rate ensures that adequate water is delivered to create a sufficient cooling effect on the surrounding space and to saturate the materials involved in a potential fire. It is designed to be effective in controlling or extinguishing a fire in its early stages, helping to minimize damage and enhance safety. Therefore, the choice of 20 gpm aligns well with established guidelines in fire protection and sprinkler system design practices.
