Straight stream vs fog pattern
Webfrom a straight stream to a wide fog pattern. Many officers and nozzle operators like having the flexibility a fog nozzle provides. this nozzle is also good for auto fires, other outside fires, and liquid petroleum fires. note that i did not say solid stream when referring to the pattern setting. at the narrowest pattern, a fog nozzle WebAs does the smooth bore nozzle, the fixed-gallonage fog nozzle maintains constant flow rate when the pump operator provides proper nozzle pressure (50 psi-100 psi) while allowing the nozzle operator to select the desired stream pattern among a wide variety of options, from the straight stream to the wide fog stream. The selectable-gallonage fog ...

STRAIGHT STREAMS Although their use in direct attack is similar, straight and solid streams have distinct differences. A straight stream is, in essence, a very narrow fog stream. It is produced by a combination nozzle and is composed of millions of tiny water droplets separated by air entrained within the stream. kcaa福岡ログインWeb• Fire stream pattern — Solid stream patterns have greater reach than straight, fog, or broken patterns. • Water droplet friction with air — Air friction has greater effect on the multiple finely-formed water droplets in a fog stream than it does on the outer surfaces of a compact solid stream. aep alberta tierWebQuality fog nozzles produce almost as good a straight stream as a solid bore nozzle but do require a higher inlet pressure.
