Surface Roughness Conversion Chart of Stainless Steel Pipe

Surface roughness —also known as surface profile Ra—is a measurement of surface finish -- it is topography at a scale that might be considered "texture" on the surface.Surface roughness is a quantitative calculation of the relative roughness of a linear profile or area, expressed as a single numeric parameter (Ra).

Energy Equation - Pressure Head Loss in Ducts, Tubes and Pipes

The major friction loss in a pipe or tube depends on the flow velocity, pipe or duct length, pipe or duct diameter, and a friction factor based on the roughness of the pipe or duct, and whether the flow us turbulent or laminar - the Reynolds Number of the flow. The pressure loss in a tube or duct due to friction, major loss, can be expressed as:
