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...
A trapezoidal channel has a bottom width 10 ft and side slope of 2H:1V. It carries a discharge of 250 cfs at a water depth of 4.8ft. The channel is to pass under a highway and a culvert is proposed for a smooth transition from the channel to the culvert. You are asked to design this transition under the following design criteria: First of all, it is important to keep in mind that the culvert shall not act as a...
(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...
#4 [5 points] A trapezoidal channel of bottom width 25 ft and side slope 1:2.5 carries a discharge of 450 cfs with a normal depth of 3.5 ft. The elevations at the beginning and end of the channel are 685 and 650 ft., respectively. Determine the length of the channel if n = 0.02. #5 [5 points] Water is flowing at a rate of 4.5 m3/s in a trapezoidal channel whose bottom width is 2.4 m and side slopes are...
A concrete-lined channel has a trapezoidal cross-section with a bottom width of 1.8 ft, side-slopes 1.5 (defined as horizontal: vertical), n the water depth is 2.7 ft, determine: (25 points) 2. 0.018, and a bed slope of 0.002 ft/ft. If a. Critica I depth (yd. Note: Because you need a solver to solve this problem (and I do not require a solving calculator for this midterm), all you need to do is set-up an equation that is in terms of...
Q2) A canal of trapezoidal section has bed width of 8 m and bed slope of 1 in 4000. If the depth of flow is 2.4 m and side slopes of the chamel are 1 horizontal to 3 vertical, determine the average flow velocity and the discharge carried by the channel. Also compute the average shear stress at the channel boundary. Take value of Chezy's constant = 55. Q3) 6.11. A power canal of trapezoidal section has to be excavated...
14.13 (a) only Spreadsheet from HW 3: Manning: 1. Numerically solve for the normal depth using either MS-Excel or Matlab. Hint: your spreadsheet for critical depth in HW3 is a good place to start. 14.13 The channel in Problem 14.7 is excavated in smooth rock to a bed slope of 0.2%. Deter- mine the (a) normal depth of flow, (b) critical slope, and (c) state of flow in the channel. 14.7 A trapezoidal channel has a bed width of 3.5...
