Sprinkler k factor calculator

For us this orifice will be a fire sprinkler head or water mist nozzle in a fire protection system, we can use the k-factor formula for almost any rounded orifice. How to derive a sprinkler performance curve using a sprinkler K factor and use. K factor (which is used with a velocityelement to calculate head loss).

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 . Sprinkler K-factor is based on the following formula: Q = Kp0. Apr 19- Water discharge is determined by the formula:.

Generally the NFPA K factor for sprinklers is K=5. Q = K√P to calculate accurate sprinkler flow. The purpose of adjusting the sprinkler K factor is ultimately to achieve a higher starting pressure for . An increase in the k-factor of a sprinkler yields a higher flow (gpm), but lower pressure.
