### What is relative roughness?What is relative roughness?Relative Roughness 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 pipefor a flowing fluid.

Within the pipe industry, there is a wide range of Mannings n values, or roughness coefficients, for various types of pipe. Several items should be considered prior to selecting an n value for a given pipe material when designing any gravity flow system. 1. Mannings n values developed for any given pipe

Consider the example of 3" PVC pipe. Absolute roughness for PVC () = 0.0015 mm Pipe nominal diameter (D) = 3" = 76.2 mm. Relative roughness of 3" PVC pipe = /D = 0.0015 / 76.12 = 1.97 × 10-5. Next this relative roughness value can be used to determine the friction factor to be used in Darcy's equation for calculating the pressure drop across a pipe.

Unfortunately, commercial pipe roughness differs from sand grain roughness in both shape and arrangement. However, Colebrook carried out experiments on commercial pipes, expressing the commercial pipe roughness in terms of an equivalent sand grain roughness size (5).Absolute Pipe Roughness - EnggCyclopedia'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.
