How fast water runs in an open channel

earth life

Manning's equation gives the velocity of water in a channel from its roughness, depth and slope — here 3.33 m/s. It sizes culverts, canals and storm drains. Worked & sealed by the engine — V = (1/0.03)·1^⅔·0.01^½ = 3.33 m/s. [HOLDS; open the seal to re-check.]
