Question 6 A concrete-lined trapezoidal channel with uniform flow has a normal depth of 1.5 m. The base width is 4 m and the side slopes are equal at 1 vertical to 2 horizontal. Mannin‘s n-0015. The bed slope 0.001 Compute the mean velocity and discharge. If the above channel were to be designed for flooding, it may have a section like in Figure below 8 m 8 m 4 m When the flow goes over the top of the...
can someone please explain how this question is solved with clear working out. 1a) Using the energy diagram explain the Standard Step method and how this method is used to,calculate water surface profiles in sub-critical flow. First begin by listing the variables whose values are normally known or given) Then using the energy diagram list the calculation method step by step. Explain the gradually varied flow assumption. 1b) A trapezoidal channel with a bottom width of 6 m, side batter...
(I) For a trapezoidal channel with a fixed cross-sectional area of 10m2, bottom width b, depth y, and side slopes of 2H:1V, confirm that the most efficient (optimal) cross-section occurs with b / У = 21 V1+ m2-m | , where ,n=2 in this case. To do this, it is easiest to make a Matlab or Excel program with different b/y ratios and 10m2 cross-sectional area, and determine the relative flow rates. Then normalize this by the optimal flow rate...
Problem 1. For the trapezoidal channel cross section shown below, find the following geometric quantities in terms of bottom width b, flow depth y, and side slope m. Provide the appropriate dimensions for each tem using the L-T-F (Length-Time-Force) system. For example, [b] L (a) Flow area, A (b) Wetted perimeter, P (c) Hydraulic radius, R (d) Top water surface width, T A (e) Hydraulic depth, D= T Problem 2. Write a function in Matlab that calculates each of the...
