2. Fire sprinkler system - Wikipedia

   en.wikipedia.org/wiki/Fire_sprinkler_system

   Water mist systems are used for special hazards applications. This type of system is typically used where water damage may be a concern, or where water supplies are limited. NFPA 750 [19] defines water mist as a water spray with a droplet size of "less than 1000 microns at the minimum operation pressure of the discharge nozzle". The droplet ...

3. Spray (liquid drop) - Wikipedia

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

   Spray nozzle manufacturers all tabulate capacity based on water. Since the specific gravity of a liquid affects its flow rate, the values must be adjusted using the equation below, where Qw is the water capacity and Spg is the specific gravity of the fluid used resulting the volumetric flow rate of the fluid used Qf.

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. Fire sprinkler - Wikipedia

   en.wikipedia.org/wiki/Fire_sprinkler

   The water stream strikes a deflector that forms the water into a spray pattern designed in support of the goals of the sprinkler type (i.e., control or suppression). Modern sprinkler heads are designed to direct spray downwards. Spray nozzles are available to provide spray in various directions and patterns.

6. 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]

7. Spray bottle - Wikipedia

   en.wikipedia.org/wiki/Spray_bottle

   Depending on the sprayer, the nozzle may or may not be adjustable, so as to select between squirting a stream, aerosolizing a mist, or dispensing a spray. In a spray bottle, the dispensing is powered by the user's efforts, as opposed to the spray can , in which the user simply actuates a valve and product is dispensed under pressure.
