A 8 m wide rectangular channel is carrying water at 180 m3/s. The channel is constructed of concrete (Manning's N = 0.013) and is laid at a slope of 0.28 %. Find the normal depth
Water flows through a rectangular channel 7.3 meter wide, at a rate of 3.1 m^3/s. with a depth of 3 meters. The channel is lined with rough concrete and has a slope of 0.075 %. Calculate the critical depth, and normal depth and classify the slope. Manning's number for the channel is 0.014.
An 8 ft. wide and 1000 ft. long prismatic rectangular channel is carrying a flow of 13 cfs. The channel has a slope of 0.001 ft/ft and Manning's n is 0.035. The depth of water in the channel is 1.25 ft. a. Another engineer computed the normal depth in the channel to be 1.25 ft, which is the existing depth of flow. Check that computation to see if it correct (show all work) b. Compute the critical depth of flow in the...

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...
A 10-m wide rectangular channel is carrying a discharge of 400 m3/s at a flow depth of 3.0 m. Determine the flow depth downstream of a step of 0.3 m if the step is: (i) a rise, and (ii) a drop. Does the water surface rise or drop downstream of the step in each case?
water flows at a rate of 20 m3/s through a rectangular channel 4.0 m wide from a "steep slope" to a 'mild slope", creating a hydraulic jump. The upstream depth of flow is 1.20 m Find the following: (a) the downstream depth of flow, (b) the energy loss in the jump, anid (c) the upstream and downstream velocities 2)
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...
A 1.7 m wide, 4000 m long rectangular channel carries 1.6 m/s of water. The depth of the flow is 0.9 m. The channel is constructed from rough-formed concrete with a roughness coefficient of n-0.015. What is the difference in elevation between the two ends of the channel?
2. A 2.5 m wide rectangular channel conveys m wide rectangular channel conveys water at a normal depth of 2 m. In a part of the channel, the channel width is expanded to 5 m. The local energy loss due to this expansion is about 10% of the upstream velocity head. If the channel slope is 0.03% and the Manning roughness coefficient is about 0.012, calculate the water depth over this transition and show the situation with a simple sketch.
