Home Up Back : TYPICAL SURFACE ROUGHNESS. Note: Pipes that have absolute roughness equal to or less than 0.000005 feet are considered to exhibit "smooth pipe" characteristics. The relative roughness of a pipe is its roughness divided by its internal diameter or e/D, and this value is used in the calculation of the pipe friction factor, which is then used in the Darcy-Weisbach equation to calculate the friction loss in a pipe for a flowing fluid. Relative Roughness The quantity used to measure the roughness of the pipe's inner surface is called the relative roughness, and it is equal to the average height of surface irregularities () divided by the pipe diameter (D). Then: GRP pipe 's head is 30.85m, while the steel's head is 58.62m. This is because the dense chromium oxide layer on the stainless steel surface prevents corrosion and surface roughness can affect this layer. 2014-2023 All Rights Reserved.
