Absolute Pipe Roughness - EnggCyclopedia

'Relative Roughness' or 'Roughness factor' of a pipe is the ratio of absolute roughness to the pipe diameter. Relative roughness factor is often used for pressure drop calculations for pipes and other equipment. The relative roughness factor is an important parameter for determining friction factor based on Reynold's number for flow in a pipe.

Absolute Roughness - piping-designer

Absolute roughness, abbreviated as \(\epsilon\) (Greek symbol epsilon), is a measure of the roughness of the inside of a flowing pipe. It is used in conjunction with the inside diameter to calculate the friction factor using a Moody Diagram, the Reynolds Number and the Darcy-Weisbach Equation. Common values for the absolute roughness are listed below.
