Fire streams reduce tempatures and provide protection during the attack
A fire stream can be defined as a stream of water that leaves the nozzle until it reaches the desired point
four elements pump hose extingishing agent nozzle

discharge pressure nozzle design nozle adjustment condition of nozzle

Fire streams used for applying water for burning fuel, reducng temp, dispersing smoke and fire gases, reducing tempature over an open fire and protecting firefighters and property
fire is extinguished or reduced, or room tempature reduced if successful

sizes - booster line, master streams and some other god damn one

types of fire streams
solid fog broken

 smooth - produced with a smooth bore orifice - a stream is effective if it does not lose continuity and doesnt lose height when a breeze is blowing
disadvantage; cannot be used to mkae different patterns

fog stream; water droplets, narrow and straight stream fog - fog nozzle 100 psi pressure forward by momentum downward by gravity
disadvantage;  do not have the reach or penetration power. if used improperly, can spread fire and upset thermal layering, and cause steam burns

broken streams can be made by a rotary distrubition nozzle, two solid streams crossing across in the air

solid stream nozzles are designed to become smaller and smaller and smaller then stopping to maximize reach and penetration. come in different shapes and sizes but share same characteristics

fog stream nozzles - create droplets by reflecting water. may have a set gallonage, or have preset gallonage settings.

water hammer - surge in system, sudden stop of flowing water. makes a sharp clank, sounds like a hammer hitting the pipe. slowly make change, not abrupt.
