Fire service friction loss formula
WebSep 1, 2024 · Consider the equation: FL = c × (gpm/100) 2 × L/100. The “c” term is the so-called friction loss factor and measures the pressure loss per 100 feet. This is multiplied by the square of the volume flow (gpm) and hose length (L) to get total friction loss. The “c” factor is a handy way of comparing results from different tests and flow rates. WebThe current formula for friction loss accounts for the diameter of the hose, the volume of water flowing, and the: (212) length of the hose layout. Which of the following is the formula for friction loss? FL = CQZL In the formula for friction loss, the "L" refers to: hose iength.
