   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.

   Water mist: This branch pipe gives a water mist. Revolving: The ball shape head of the branch pipe is fitted with many small nozzles pointing in different directions and the head rotates when water passes through it. This creates a rotating jet at different angles. It is used for fighting a ship fire or enclosed shaft fire.

   New York, 1890–1930 Example of a vintage atomizer nozzle Principle of operation of an atomizer. A spray nozzle or atomizer is a device that facilitates the dispersion of a liquid by the formation of a spray. The production of a spray requires the fragmentation of liquid structures, such as liquid sheets or ligaments, into droplets, often by ...

   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.

7. Nozzle - Wikipedia

   en.wikipedia.org/wiki/Nozzle

   A nozzle is a device designed to control the direction or characteristics of a fluid flow (specially to increase velocity) as it exits (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid ( liquid or gas ).
