Calculate the pipe friction factor using this application,
The calculator allows you to calculate the Darcy friction factor also commonly obtained from the Moody chart and also calculate the Fanning friction factor.

The calculator will request the following input:
Reynolds' Number, Pipe Diameter and the Pipe Surface Roughness

The calculated result produces the following output:
Relative Roughness
Darcy Friction Factor
Fanning Friction Factor

There are two different equations that the calculator uses based on user choice,
You can choose from either CHURCHILL EQUATION or COLEBROOK-WHITE EQUATION
The App will do iteration to compute the friction factor if the Colebrook-White equation is used.
Both equations produce a close estimate and would save time instead of looking up charts.

The App accepts input in two different units, SI Units and US Units. There is a small database for different pipe materials that include values for Surface Roughness taken from literature,
The material list is below:
Copper, Glass, Plastic, Brass, Iron, Steel, Concrete, Rubber
