Steel pipe roughness table
網頁Cis a measure of the roughness of the interior of the pipe. Expressed in terms of C, the formula can be stated several ways. Once such way is stated as: C= 2,466QD–2.63 H0.54L0.54 (Eq. 1-2) where: C= Hazen–Williams roughness coefficient Q= quantity of flow in a pressure conduit, mgd (m3/d) D= nominal diameter of the pipe, in. (mm) 網頁The roughness is actually a measurement of all the asperities at the surface of a material, especially a pipe where it will oppose the flow of fluid. The following table is summarizing …
