WebThere are many ways to estimate the friction loss in fire hose. Methods like the old hand, new hand, drop 10, and the condensed “Q” are just a few that you may have learned. Conceivably, the most accurate method to determine friction loss is to conduct your own tests. By doing this you will know, with almost exact WebFRicTiON LOSS in the fire service, friction loss is defined as the loss of energy in pressure whenever water runs through hoses, fittings, and appliances. as water runs through hose, it rubs Table 1.
