App description

Enter the value and click "Calculate" to display the result

Calculation formula:

f_T = Turbulent friction factor

L = length

D = pipe diameter

K = K value

Usage example

Input data:

Turbulent friction factor: 45

Length: 60m

Pipe diameter: 10mm

Click "Calculate" to output data

K value: 270.000

Note

This calculator calculates the tube diameter change, the K value of the L/D coefficient valve. The L/D factor is stored in the valve table for the tube diameter range. These valves are butterfly valves and swash plate type check valves.
