The roughness of a pipe is normally specified in either mm or inches and common values range from 0.0015 mm for PVC pipes through to 3.0 mm for rough concrete pipes. Relative Roughness. The relative roughness of a pipe is its roughness divided by its internal diameter or e/D, and this value is used in the calculation of the pipe friction factor, which is then used in the Darcy-Weisbach equation to calculate the friction loss in a pipe for a flowing fluid.

If the pipe is circular, you will find it according to the following equation R = A / P = r² / 2r = r / 2 = d / 4. where r is the pipe radius, and d is the pipe diameter. You can view and modify all these parameters (area, perimeter, hydraulic radius) in the advanced mode of this pipe flow calculator.
