Coefficient of friction
, What is the best method to prevent waterhammer?
Open and close valves and nozzles slowly
A surge of energy moving the opposite direction caused by suddenly stopping water
moving through a hose or pipe is called:
Water Hammer
Any pressure that is less than atmospheric pressure (102.9 kPa)
Vacuum
The part of the total available pressure not used to overcome friction loss or gravity
Residual pressure
Stored potential energy (pressure) available to force weather through hoses when water
isn't moving:
Static pressure

nozzle effectively:
Nozzle Reaction
If a firefighter operating a nozzle turns the setting from 950 L/min to 450 L/min without
telling the pump operator, they will be:
Increasing the friction loss
