Manning's n for concrete pipe

Web04. okt 2024. · Design Data 10: Manning's N Values - History of Research. Selection of the proper value for the coefficient of the roughness of a pipe is essential in evaluating the flow through culverts and sewers. An excessive value is uneconomical and results in oversizing of pipe, while equally, a low value can result in a hydraulically inadequate pipe.
