A rectangular river channel 5.0m wide carries water at a depth of 1.2m. The slope of the channel is 1 in 400. The channel has a bed covered with stones. Using the n value of 0.03(s/m1/3) calculate the discharge in the channel using Manning’s equation
Water flows down a rectangular channel that has a width of 2.2 m, a Manning's n of 0.019 and a slope of 1 in 200. Calculate the discharge in the channel when the depth of flow is 0.5 m, 1.0 m, 2.0 m, and 4.0 m. Plot a graph of depth against discharge and comment on its shape, [10 marks] A wide channel has a Manning's number = 0.021, a longitudinal bed slope of 1:250 and conveys 0.XX m3/s/m of...
QUESTION 4 What is the normal depth in a 4-foot wide rectangular channel that conveys a discharge of 133 cfs and has a bed slope of 2.0% with a Manning's roughness coefficient of 0.025? a. 1 40 foot 6.2.10 feet c. 2.71 feet O d. 3.39 feet e. 4.40 feet
9) A rectangular channel 8 feet wide carries 2.5 ft/s of water at a depth of 3.2 feet. What are the most efficient attributes (d, A, P, and R) of the channel?
9) A rectangular channel 8 feet wide carries 2.5 ft/s of water at a depth of 3.2 feet. a) What are the most efficient attributes (d, A, P, and R) of the channel? b) If a 1-foot wide pier is placed in the middle of the channel, find the elevation of the water surface at the pier. What is the minimum width of the constriction that will not cause a rise in the upstream water surface?
Specific discharge of a wide rectangular channel is 10.0m2/s (Q 10.0m3/s/m). The channel consists of two long reaches having the following bed slope, So1 -0.0001 (for ABC), and So2 = 0.008 for (CDE), (see Figure 1) respectively. There are two gates to control the flow and the flow depth at the vena contractor after each gate is approximately 0.3m. Take the Manning's coefficient as 0.015 Locate every possible flow changing locations and, sketch and name the water surface 1. profiles...
please help! 9. In a uniform flow taking place in a wide rectangular channel at a depth of 1.2 m, the velocity is found to be 1.5 m/s. If a change in the discharge causes a uniform flow at a depth of 0.88 m in this channel, the corresponding velocity of flow would be (a) 0.89 m/s (b) 1.22 m/s (c) 1.10 m/s (d) 1.50 m/s (e) 2.50 m/s 10. A triangular section is hydraulically efficient when the vertex angle...
please show all the steps thank you 2. Water flowing at the normal depth in a rectangular concrete channel that is 12 m wide encounters an obstruction, causing the water level to rise above the normal depth at the obstruction and for some distance upstream. The water discharge is 126 m3/s, and the channel bottom slope is 0.00086. If the depth of water just upstream from the obstruction (yo) is 4.55 m, find the distance upstream to the point where...
Please Answer: 3, 7-9 QUESTION 1 Cougar Run flows from the west to the east (see figure below showing the location of the river, your factory, a factory built in 2004, local farms (A-F), and water wells). Based on the shape of the stream channel, consider where one would expect significant erosion or deposition to occur. Based on your evaluation of the the figure below, which landowners (A-F) could experience the worst erosion damages to their property? Owell well Cougar...
