An example used would be a fast-food restaurant that is 70 feet wide. The design area shall include a minimum operating area of 1,200 square feet (111.5 sq m)." Required flow in gpm equals length times width times the number of floors involved divided by three (GPM L x W x floors 3).
The design area shall consist of the hydraulically most demanding area of 15 sprinklers, consisting of five sprinklers on each of three branch lines. In Table 12.4.2(d), change the number of sprinklers in the 25.2 Nominal K-factor rows from "12 (see Note 3)" to "15 (see Note 6)" and add the following Note 6: This chart indicates the flow in GPM that a pipe size can generally handle: Pipe Size.

The flow exits through a nozzle contraction at a diameter Dn. Be careful with specific state requirements as well. 4 A fire hose has a 5-inch inside diameter and is flowing at 600 gal/min.
