Web24 dec. 2024 · The formula for computing hydraulic mean depth or hydraulic radius is: R = A / P Where: R = Hydraulic Depth A = Cross-sectional Area of Flow P = Wetted Perimeter For Example: Find the hydraulic mean depth or hydraulic radius of flow in an open channel where the cross-sectional area is 150 m 2 and the wetted perimeter is 100 m. WebAnswer:normal depth = 1.24 m; critical depth = 0.972 m. (c) To determine the type of behaviour over the raised bed, compare the total head under critical conditions (the minimum energy necessary to get over the weir at this flow rate) with that available in the approach flow. Critical ℎ =0.9717 m 𝐸 = 3 2 ℎ =1.458 m 𝑧 =0.8 m 𝐻 =𝑧 +𝐸 =2.258 m
