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.
Surface coefficients to calculate flow friction and major pressure loss - surfaces like concrete, galvanized steel, corroded steel and more Sponsored Links For turbulent flow the friction coefficient depends on the Reynolds Number and the roughness of the duct or pipe wall.(PDF) Surface-Roughness Design Values for Modern PipesSurface-Roughness Design Values for Modern Pipes. , 37mm carbon steel pipe roughness carbon steel to pipes made with different alloys and internal sur- , 37mm carbon steel pipe roughness Roughness of coated pipe was assessed with two linear surface profilers , 37mm carbon steel pipe roughnessPipe Roughness - Industrial Professionals - Cheresources , 37mm carbon steel pipe roughnessPipe Roughness - posted in Industrial Professionals: Dear All, The NORSOK standard P-001 provides following guidelines for estimation of pressure drop in CS piping : carbon steel (non corroded) : 0.05 mm carbon steel (corroded) : 0.5 mm Other reference on web/text books also specify a value in betwen these two extremes.

It is quantified by the vertical deviations of a real surface from its ideal form. If these deviations are great, the surface is rough, if they are small, the surface is smooth. Roughness is typically considered to

The internal roughness of a pipe is an important factor when considering the friction losses of a fluid moving through the pipe. For each pipe material either a single pipe roughness value or a range of roughness values is normally provided by the , 37mm carbon steel pipe roughness
