29-page PDF document about calculating friction loss, it also includes formulas, examples and Friction loss coefficients.
An article about the friction loss. It refers to that portion of pressure lost by fluids while moving through a pipe, hose, or other limited space. In mechanical systems such as internal combustion engines, it refers to the power lost overcoming the friction between two moving surfaces.
An article that provides formula for calculating friction loss on water such us: smooth-bore pipes and channels.
An article about the smooth bore pipe general purpose hose which reduces friction loss and internal abrasive wear, but additional savings can be realized if sharp elbows and turns are avoided.
An article about calculating friction loss in fire hose. Friction loss refers to the amount of energy that water loses as it travels through a hoseline, the couplings, and the nozzle. This loss of energy must be compensated for by the pump operator to ensure that the nozzles are being supplied with the correct operating pressure. In order to determine the amount of friction loss in a given hoseline, a mathematical formula is used.
