Fire Hose Gpm Chart

Fire Hose Gpm Chart – For more fire protection resources visit www.meyerfire.com/subscribe. Flow tests give you specifics on the gpm and pressure requirements for different evolutions and equipment such as hose nozzles and appliances. Blitzfire flow chart friction loss for 2 1/2 inch hose (psi) hose length in feet flow (gpm) 150 200 250 300 350 400 100 345678 150 7 9 11 14 16 18 200 12 16 20 24 28. Divide the total friction loss by the length of the supply line (per 100 feet).

The readings on this chart are based on pitot diameter orifice. The equation ep = np + fl + app + elev is the basic equation every pump operator needs to calculate when operating the fire pump. By using a pump chart (table 1), determine the gpm by the hose size and the friction loss per 100 feet. Flow (gpm) using a 0.90.

These sizes always seem to be the first hoselines pulled for any offensive fire. This chart shows the relationship between rate of flow,i.d., and the pressure loss the pressure loss is directly proportional to the length of the hose, therefore the data shown. The gpm (gallons per minute) calculator is an excel spreadsheet that helps you calculate the amount of water that a fire hose needs to deliver in order to suppress.

This article is going to talk about specific tests that can be done as well. Fl = friction loss coefficient x (flow rate / 100)2 x (hose length / 100) or. Posted july 2021 on meyerfire.com.

Friction loss occurs when water passes through a fire hose. In most cases, the flow will be 500 gallons per minute (gpm) or less. 60 / 5 = 12.

The formula to find gpm is 60 divided by the seconds it takes to fill a one gallon container (60 / seconds = gpm). I’ve googled and looked everywhere without success for a chart, or listing of flow capacities for fire hose for these sizes 1 3/4, 2 1/2, 3, and 5. Today, many pump panels have flow.
