K Factor Calculator
Result
K Factor Calculator Calculate the K-factor for fire sprinklers (K = Q / √P) or sheet metal bending K-factor. — free online calculator.
Formula
- K Factor Calculator calculates its result from Q, Principal, Neutral Axis Offset, Material Thickness. It uses the formula Sprinkler: K = Q / √P; Sheet metal: K = neutral axis offset / material thickness. Change any input to recalculate the result instantly.
- The main inputs are Application, Flow Rate Q, Pressure P, Neutral Axis Offset, Material Thickness. Enter them in the units and format shown in the calculator.
- Keep measurements and project assumptions consistent before comparing or combining values.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: K Factor
- Application: sprinkler
- Flow Rate Q: 20
- Pressure P: 10
- Neutral Axis Offset: 0.1
- Material Thickness: 0.125
Using Q = 2, Principal = 3, Neutral Axis Offset = 4, Material Thickness = 5, the calculated result is 0.8.
