Firefighter training friction loss premium pump operations water supply. Gallon per minute flow, which is the major factor causing friction loss in fire hose. How to calculate friction loss in fire hose.

All friction loss factors are computed in 100 foot lengths of hose. Determine the friction loss in the intake hose used 3. Fire hose friction loss cheat sheet. Friction loss in fire hose is governed by the following rules:

Fire Hose Friction Loss Cheat Sheet

Firefighting involves a little bit of math from time to time. Add lift and friction loss together 4. Friction loss occurs when water passes through a fire hose.

Divide by 2.3 (2.3 is the amount of lift (in feet) that 1psi of. 1 friction loss varies with the quality of the hose. Determine the lift (in feet) 2.

The friction loss is needed in conjunction with the nozzle operating pressure and elevation loss (or gain) to determine the proper pump discharge pressure (pdp=np +. (2) friction loss may vary with brand and condition of hose. Use this as a fire hose friction loss cheat sheet.

These will give you the fl for a certain gpm measurement, which you can then use. Friction loss for a fire hose is calculated using various formulas that take into account factors like hose diameter, hose length, flow rate, and the characteristics of. From figuring out pump discharge pressure to nozzle reaction, there are some.
