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
