2. Hydraulic calculation - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_calculation

   The hydraulic calculation procedure is defined in the applicable reference model codes such as that published by the US-based National Fire Protection Association (NFPA), [2] or the EN 12845 standard, Fixed firefighting system – Automatic sprinkler systems – Design, installation and maintenance. [3]

3. Fire sprinkler system - Wikipedia

   en.wikipedia.org/wiki/Fire_sprinkler_system

   A fire sprinkler system is an active fire protection method, consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system, to which fire sprinklers are connected. Although initially used only in factories and large commercial buildings, systems for homes and small buildings are now available ...

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. Pipe network analysis - Wikipedia

   en.wikipedia.org/wiki/Pipe_network_analysis

   Once the friction factors of the pipes are obtained (or calculated from pipe friction laws such as the Darcy-Weisbach equation), we can consider how to calculate the flow rates and head losses on the network. Generally the head losses (potential differences) at each node are neglected, and a solution is sought for the steady-state flows on the ...

6. Fire sprinkler - Wikipedia

   en.wikipedia.org/wiki/Fire_sprinkler

   A fire sprinkler mounted on a ceiling. A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been exceeded. Fire sprinklers are extensively used worldwide, with over 40 million sprinkler heads fitted each year.

7. Hazen–Williams equation - Wikipedia

   en.wikipedia.org/wiki/Hazen–Williams_equation

   It is used in the design of water pipe systems [1] such as fire sprinkler systems, [2] water supply networks, and irrigation systems. It is named after Allen Hazen and Gardner Stewart Williams. The Hazen–Williams equation has the advantage that the coefficient C is not a function of the Reynolds number , but it has the disadvantage that it is ...
