2. Spray nozzle - Wikipedia

   en.wikipedia.org/wiki/Spray_nozzle

   Spray nozzles can have one or more outlets; a multiple outlet nozzle is known as a compound nozzle. Multiple outlets on nozzles are present on spray balls, which have been used in the brewing industry for many years for cleaning casks and kegs. [2] Spray nozzles range from those for heavy duty industrial uses to light duty spray cans or spray ...

4. Nozzle - Wikipedia

   en.wikipedia.org/wiki/Nozzle

   Atomizer nozzles are used for spray painting, perfumes, carburetors for internal combustion engines, spray on deodorants, antiperspirants and many other similar uses. Air-aspirating nozzles use an opening in the cone shaped nozzle to inject air into a stream of water based foam (CAFS/AFFF/FFFP) to make the concentrate "foam up".

5. Fog nozzle - Wikipedia

   en.wikipedia.org/wiki/Fog_nozzle

   A fog nozzle. A fog nozzle is a firefighting hose spray nozzle that breaks its stream into small droplets.By doing so, its stream achieves a greater surface area, and thus a greater rate of heat absorption, which, when compared to that of a smoothbore nozzle, speeds its transformation into the steam that smothers the fire by displacing its oxygen.

6. K-factor (fire protection) - Wikipedia

   en.wikipedia.org/wiki/K-factor_(fire_protection)

   In fire protection engineering, the K-factor formula is used to calculate the volumetric flow rate from a nozzle. Spray nozzles can for example be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles.

7. Propelling nozzle - Wikipedia

   At the other extreme, some high bypass ratio civil turbofans control the fan working line by using a convergent-divergent nozzle with an extremely low (less than 1.01) area ratio on the bypass (or mixed exhaust) stream. At low airspeeds, such a setup causes the nozzle to act as if it had variable geometry by preventing it from choking and ...
