In fire protection engineering, the K-factor formula is used to calculate the discharge rate from a nozzle. Nozzles can be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles.
The flow rate of a nozzle is given by [1], where q is the butts flow rate in litres per minute (LPM), p is the pressure at the nozzle in Bar and K is the K-factor is given in units of .
