About:K-factor (fire protection)

An Entity of Type:Thing,from Named Graph:http://dbpedia.org,within Data Space:dbpedia.org

In fire protection engineering, the K-factor formula is used to calculate the discharge rate from a nozzle. Spray Nozzles can be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles. K-Factors calculated in Metric units; The flow rate of a nozzle is given by , where q is the flow rate in litres per minute ( l/min ), p is the pressure at the nozzle in Bar and K is the K-factor is given in units of . Care should be exercised not to intermix K-factors from Metric and Imperial/US units as the resulting factors are not equivalent or interchangeable.

  • In fire protection engineering, the K-factor formula is used to calculate the discharge rate from a nozzle. Spray Nozzles can be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles. K-Factors calculated in Metric units; The flow rate of a nozzle is given by , where q is the flow rate in litres per minute ( l/min ), p is the pressure at the nozzle in Bar and K is the K-factor is given in units of . K-Factors have also been calculated and published in US units of PSI and GPM. Within the United States, only US measurements (PSI, and US-Gallons per minute) are used. Care should be exercised not to intermix K-factors from Metric and Imperial/US units as the resulting factors are not equivalent or interchangeable. (en)
