How do you calculate K factor sprinklers?
K-Factor formula for fire sprinklers
- Q = AV.
- Q = A√(2gh)
- q = kp0.5
- k = q / p0.5
- p = ( q / k )2
- for metric calculations: p = pressure in bar. q = flow in litre per minute. k = discharge constant Lpm/bar0.5
- and for imperial calculation: p = pressure in psi. q = flow in gpm. k = discharge constant gpm/psi0.5
What is the K factor of a nozzle?
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.

When the size of a sprinkler orifice gets bigger the K factor?
SPRINKLER SIZE AND RESPONSE TIME The K-factor increases as the orifice size of the sprinkler increases. The K-factor for a standard 1/2 inch sprinkler is 5.6.
What is K value for sprinkler?
The k-factor for a fire sprinkler is the discharge coefficient, or in normal human terms just relates to the amount of water that is permitted through the sprinkler. The k-factor is dependent upon the orifice diameter of the sprinkler – a low k-factor (such as K2.
What is K-factor in flow measurement?
From Wikipedia, the free encyclopedia. For aircraft fuel flow meters, K-factor refers to the number of pulses expected for every one volumetric unit of fluid passing through a given flow meter, and is usually encountered when dealing with pulse signals.
What does k-factor mean in sprinklers?
discharge coefficient
The k-factor for a fire sprinkler is the discharge coefficient, or in normal human terms just relates to the amount of water that is permitted through the sprinkler. The k-factor is dependent upon the orifice diameter of the sprinkler – a low k-factor (such as K2.
What is k-factor in orifice?
Essentially, the k-factor is the orifice size needed for a particular flow and pressure. Low k-factors have a smaller diameter and restrict the flow while larger k-factors allow for more flow. Meyer Fire offers a tool to compare pressure requirements and flow rates for different k-factors.
How do I calculate sprinkler flow?
Finding the Flow Rate or GPM
- Equation: 5 (gallons)/number of seconds to fill, then multiply your answer by 60 to get gpm.
- Example: It takes you 30 seconds to fill a five-gallon bucket; 5/40 = 0.167, 0.167 x 60 = 10 gpm.
