The procedure is to first determine the equivalent sand roughness h from Table 9.1 based on the nature of the surface in question and then to determine the roughness parameter l/h using the length l of the component being analyzed. Then, using Equations (9.9) and (9.10), depending upon the speed range under consideration, determine the cut-off Reynolds number.
