fT = turbulent friction factor
L = length
D = pipe diameter
K = K value
Valve manufacturers have conducted experimental various valves and fittings to derive the exact type of piping pressure system expression for the piping system components.
This calculator shows the relationship between the K value and the tube length.
The K values of various accessories are tested. For any valve, the length of the diameter (L / D) factor can be determined by the pressure drop across the valve to the equivalent length of the pipe diameter measuring tube.
