What is fire hose friction loss?
Friction loss is when the water inside the hose rubs against the inner lining and losses velocity as it reaches it destination. So when water is pumped through a hose it losses speed b/c of it rubbing against the inside of the hose. AKA Fri... Read More »

How to Calculate Friction Loss in a 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 wi... Read More »
