  • Absolute Pipe Roughness - EnggCyclopedia

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