Water flows in a 100 ft wide rectangular channel at flow rate = 300 ft3/sec. Manning's n = 0.015 and the bottom slope = 0.002. Calculate/answer the following: a. the uniform (normal) flow depth assuming the channel is wide and shallow. b. the critical flow depth. c. the flow depth upstream of a hydraulic jump with downstream depth = normal depth. d. the type of channel slope at the given normal depth: mild, critical, or steep (select one). f. the basis for your answer in...
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...
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...
