Web2. Friction loss is the reduction of water pressure which occurs as water travels over distance and through any kind of restriction. Following is the formula for friction loss (FL) in a 2 ½ inch fire hose: FL = 2Q2 + Q where: Q = GPM/100 Based on the information given above, what is the friction loss of a 2 ½ inch hose WebFRICTION LOSS (FL): PDP = NP +/-H + FL The next element in the PDP formula is friction loss (FL). When moving water comes in contact with the inner lining a hose, a loss of energy will occur due to friction. This energy loss is expressed in pounds per square inch loss. This friction results in an eddying of the water or turbulence within the hose.
