Definitions for "Friction Loss"
Keywords:  turbulence, pipe, gpm, hose, velocity
The loss of pressure or head due to the resistance to flow in the pipe and fittings. Friction loss is influenced by pipe size and fluid velocity, and is usually expressed in feet of head.
The loss of pressure caused by the turbulence created in water while traveling through the pipe.
Water rubbing against the system components resulting in accumulated pressure loss from the source to the nozzle.
