Aug 13, 2007Pipe 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. My question is that what roughness value should be considered What is absolute pipe roughness?What is absolute pipe roughness?Absolute Pipe Roughness is usually defined for a material and can be measured experimentally. Following table gives typical roughness values in millimeters for commonly used piping materials.Absolute Pipe Roughness - EnggCyclopedia What is relative roughness?What is relative roughness?Relative roughness. 'Relative Roughness' or 'Roughness factor' of a pipe is the ratio of absolute roughness to the pipe diameter.

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.

Steel pipe, on the other hand, has a Hazen-Williams roughness coefficient of 120 when new, or 65 used. The far greater loss in smoothness for the steel pipe is due to scale build-up on the steel pipe.Friction factor and pipe roughness (fluids.friction carbon pipe roughnessFriction factor and pipe roughness (fluids.friction)¶ fluids.friction.friction_factor (Re, eD=0.0, Method='Clamond', Darcy=True) [source] ¶ Calculates friction factor.
