A rectangular channel with a base width of 3 m carries a discharge of 6 m3/s...

A rectangular channel with a base width of 3 m carries a discharge of 6 m3/s at a depth of 1.1 m. At downstream, there is a gradual rising of a channel bed of 0.1 m. a) Plot the specific energy curve from y = 0.4 m to 1.3 m in a step 0.1 m and from the curve, determine the depth of flow at the downstream section. Label the graph and show your working answers clearly on the graph....

A 5 m wide rectangular channel carries a flow of 20 m3/s. The slope of the channel is 0.005 and the Manning’s n is 0.03. The flow encounters a 0.5 m step up that is 0.1 m long. The depths far upstream and downstream are normal. Classify this channel Qualitatively sketch this scenario, label gradually varied flow curves and provide appropriate depths. Draw this scenario on an E-Y cycle graph, and label all depth changes.

The discharge through a rectangular channel 4.4 m wide is 16 m3/s. The Manning’s coefficient n is 0.03. Determine the normal depth when the slope is 0.008. Check whether the flow is sub or supercritical. If the normal depth is to be kept at 2 m, determine the slope.

13.(LAB) A discharge of 25 m3/s is passing in a rectangular channel of bed width 8.0 meters and water depth 3.0 meters. The channel bed width is gradually contracted from 8.0 meters at section (1) to 6.0 meters at section (2). In the contraction zone, a smooth hump is placed in the channel in which the bed level is gradually increased by 1.00 m. Determine: (i) The change in water levels, (ii).The minimum height of hump so that y2 =...

A 50 m3/s is conveyed down a 5-m wide rectangular channel (n = 0.012) with a slope of 0.02 m/m. The channel transitions into a second channel with a slope of 0.0008 m/m. A hydraulic jump occurs on the downstream channel. What is the downstream depth of the second channel after the jump? What is the depth of the water before the jump? What is the energy loss due to the jump? How long is the total distance of the...

Design a trapezoidal channel to pass a discharge of 10m3/s and the channel will be excavated through rock by blasting. The topography in the area is such that a bottom slope of 1 in 4000 will be suitable. Assume that n = 0.030 and select a value for the side slope, Z, as 1 horizontal to 4 verticals. Sketch the diagram for all calculated dimensions.
