Subcritical, uniform flow of water occurs in a rectangular, horizontal channel with a width of 5.0 m. The flow has a depth of 2.0 m and a flow rate of 5.0 cu.m/s. The flow encounters a 0.25 m rise in the channel bottom. What is the new normal depth? Is the flow above the rise subcritical, critical or supercritical? Assume frictionless flow
solve all 4 parts please
Water discharging into a 12-m-wide rectangular horizontal channel from a sluice gate is observed to have undergone a hydraulic jump. The flow depth and velocity before the jump are 0.9 m and 9 m/s, respectively. Determine (i) Froude number before the hydraulic jump. Is it subcritical, critical, or supercritical flow? (4 points) (ii) the flow depth and the Froude number after the jump. Is it subcritical, critical, or supercritical flow? (9 points) (iii) the head...
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...
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...
A 12-ft-wide rectangular channel conveys 3,030 cfs. Determine the normal and critical depths for the concrete channel (1% slope). Also determine the flow classification (critical, supercritical, or subcritical) when the channel flows at normal depth.
Answer and progress.
A hydraulic jump occurs in a rectangular channel 3.0m wide. The water depth before the jump is 0.6m, and after the jump is 1.6m. Find the followings: (a) the flow rate in the channel Q = m/s (b) the critical water depth yc = m (c) the head loss in the jump, h = m
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...
Uniform water flow in a wide brick channel of slope 0.02 degrees moves over a 10-cm bump. A slight depression in the water surface results. If the minimum water depth per meter of width Then, again assuming uniform subcritical approach flow (V., y find (c) the flow rate and (d) y2 for which the flow at the crest of the bump is exactly critical (Fr2-10)

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?
