2. Spray nozzle - Wikipedia

   en.wikipedia.org/wiki/Spray_nozzle

   A wide variety of spray nozzles exist, that make use of one or multiple liquid breakup mechanisms, which can be divided into three categories: liquid sheet breakup, jets and capillary waves. Spray nozzles are of great importance for many applications, where the spray nozzle is designed to have the right spray characteristics. [1]

3. Spray (liquid drop) - Wikipedia

   en.wikipedia.org/wiki/Spray_(liquid_drop)

   The drop size is the size of the spray drops that make up the nozzle's spray pattern. [7] The spray drops within a given spray are not all the same size. There are several ways to describe the drop sizes within a spray: • Sauter Mean Diameter (SMD) or D32 Fineness of spray expressed in terms of surface area produced by the spray.

4. 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.

5. Ultrasonic nozzle - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_Nozzle

   An atomized spray produced from an ultrasonic nozzle is subjected to a heated substrate typically ranging from 300–400 degrees C. [23] Due to the high temperatures of the spray chamber, extensions to the ultrasonic nozzle (as pictured and labeled – High Temperature Ultrasonic Nozzle) [citation needed] such as a removable tip (tip is hidden ...

   Simple: Creates a simple jet as per size of diameter of nozzle. Diffuser: The nozzle of branch pipe rotates. If we rotate it to one side, it creates a spray of water; and at the end of rotation, it gives a water curtain to protect the firefighters when direction of wind changes while fighting a fire.

7. 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".
