Wall Factor and D of Bend Creating Quality Bends with d pipe factor d steel pipe

"D" of Bend. The second relationship to evaluate is D of bend (yes, that is the technical name). This is the ratio between the centerline radius of the bend and the outside diameter of the material. The rules for this relationship are opposite of those for wall factor. When it comes to D

Pipe Friction Calculation for Fluid Flow in a Pipe

Note that Dz will be negative if the pipe at B is lower than at A. The viscous head term is scaled by the pipe friction factor f. In general, f depends on the Reynolds Number R of the pipe flow, and the relative roughness e/D of the pipe wall, The roughness measure e is the average size of the bumps on the pipe
