The real underlying factor for pressure at the nozzle is the pressure being supplied by the hose. Hence the fire department's use of PUMPER TRUCKS to pump up the pressure. The Plain Pipe type of nozzle is merely a tapered restriction at the end of the hose that maintains the pressure at the tip by restricting the flow. The more professional type of fire fighting FOG nozzles are much more complicated internally. (Some are even designed to maintain a constant gallonage flow through the nozzles.) These nozzles are designed to break the stream up in one fashion or another in order to create small droplets and thereby increase surface area of the water thereby helping to cool the fire.<br><b>References : </b><br>30 years in the hose & coupling industry 20 years marketing manager for fire equipment That all depends on the type of fire fighting hose nozzle you have.

The nozzle also contains a valve that controls the flow of the water by moving a lever forwards or backwards. It's almost like a garden hose.<br><b>References : </b><br> Well, since there is a LOT of water flowing through the hose and trying to exit at one spot, so it’s going to build up water pressure.
