WebColebrook White Roughness Coefficient. The Colebrook White Roughness Coefficient or equivalent sand roughness coefficient is a coefficient describing the internal roughness of the drainage pipe. It is used in the Colebrook White Equation. While this coefficient may have the units of length it cannot be measured directly from the pipe.
