#### Friction loss

Description:

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.

#### How to Calculate Friction Loss in a Fire Hose

Description:

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.
