What is roughness coefficient ?

The roughness coefficient, often represented as Manning's n, quantifies the resistance exerted by the interior surface of a channel or pipe on the fluid flow. It accounts for factors like surface texture, material, and any irregularities. This coefficient is crucial in hydraulic calculations, as it directly affects flow velocity, discharge, and energy loss. Accurate determination of the roughness coefficient is essential for designing efficient water conveyance systems and predicting flow behavior.
