K Value and Pipe Length Calculator

Valve manufacturers have conducted experiments on a variety of valves and fittings to derive empirical pressure drop expressions for specific types of piping system components.

This calculator shows the relationship between K value and tube length.

The K value of various accessories is by experiment. For any valve, the length in diameter (L/D) coefficient allows the determination of the equivalent length of pipe by measuring the pressure drop across the valve versus the pipe diameter.
