Oct 15, 2010· I am currently calculating pressure losses through my oil circuit and would like to know if anyone has typical absolute roughness values to use for hydraulic hoses? I am using Aeroquip hoses -16 (1 inch) size. I read somewhere that 0.0001 feet is a conservative number to use? Does anyone have technical info on this? Regards, Gabriel
Passivation, in physical chemistry and engineering, refers to a material becoming "passive," that is, less affected or corroded by the environment of future use. Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build from spontaneous oxidation in the air.

'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.

Roughness measurements of stainless steel surfaces Introduction Ra value Surface roughness is a measure of the texture of a surface. 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
