L/D Varies with Pipe Diameter Calculator

Usage example
Input data:

Turbulent friction factor: 45

Length: 60m

Pipe diameter: 10mm

Click "Calculate" to output the data

K value: 270.000

Precautions
This calculator calculates, pipe diameter changes, L/D coefficient K value of the valve. The L/D coefficient is stored on the valve table for the pipe diameter range. Valves belonging to this type include butterfly valves and swash plate check valves.
