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?
A rectangular channel 3 m wide carries 4m3/s of water at a depth of 1.5m. if an obstruction 15 cm high is placed across the channel, calculate the elevation of the water surface over the obstruction.
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
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.
Water flows through the 4-ft wide rectangular channel at a rate 30 ft3/s. The depth of water upstream the potential hydraulic jump is 1 ft. Show a labelled illustration of the channel based on the information provided. Determine whether the hydraulic jump will form or occur. If the jump occurs, evaluate its depth, y2 and its corresponding Froude number. Evaluate the energy head loss in the jump and relative to initial energy head, do you think this head loss is...
A 10 ft wide rectangular channel is constructed of planed wood. The bottom slope is 0.000, and it carries a flow rate of 55 cu. ft/s of water. At Section 1 the depth is 2.50 ft, and at Section 2 the depth is 2.0 ft. Which section is located upstream from the other?
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...
