PLEASE SOLVE PARTS (E) AND (F) Problem: Open-Channel Hydraulics: Flow Profiles, Direct Step Method and Hydraulic JumpA rectangular concrete channel is 60 feet wide, has a bed slope of 3 per thousand and a Manning's friction factor nof 0.015.NDL-(a) The 100-year design flow is Q = 300 cfs. Compute the normal depth y, in the channel.(b) Is the uniform flow in the channel subcritical or supercritical? Show your calculations.(c) There is a sluice gate at the downstream side of the channel. It induces a rise in water surface elevationupstream of the sluice gate. The depth of water upstream of the gate is 2.5 ft. Which gradually variedcurve (M1, M2, M3, S1, S2, S3, etc.) is formed upstream of the sluice gate? Plot it on the scchematic diagrambelow.(d) Use the Direct Step Method to compute the length (L) of the gradually varied flow curve that was identifiedin question (c). You can use Excel to compute the length of the curve. (I suggest you use incremental depthchanges of Dy=0.1 ft between y=2.5 ft and y, in order to find Dx for each step.)(e) The flow Q = 300 cfs goes under the sluice gate that extends across the width of the channel. The openingunder the sluice gate is 0.2 ft. The water flow continues in the same channel with the same bed slope andcross section. Show the gradually varied curve after the sluice gate. Is it M1, M2, S1, or...?(f) Does a hydraulic jump form anywhere in the channel? Explain why and where. If there is a hydraulic jump,compute the alternate depths y₁ and y₂ before and after the jump, and mark them on the diagram.(NOT TO SCALE)BED SLOPE Sy=2.5°$0.2•SLUICEGATENDL

Consider a rectangular cross-section beam having width b and height h that is taking bending load. The beam can be oriented in two different ways (shown in case a and b), and the corresponding neutral axes are shown as well. In which case, the beam will provide more resistance to bending (i.e., larger value of 1)? b Case (a) Neutral axis O I. Case (b) O II. Depends on other parameters III. Case (a) IV. Both cases will give the same value of I Case (b) Neutral axis

The beam cross section shown below has been proposed for a short pedestrian bridge. The cross section will consist of two pipes that are welded to a rectangular web plate. Dimensions of the cross section are: h= 430 mm tw= 12 mm d= 110 mm t= 9.6 mm Additionallv: • The area of each pipe is A = 3028 mm2. • The moment of inertia of the entire beam cross section about the z centroidal axis is I>= 320410000 mm4. If the beam will be subiected to a shear force of V = 110 kN, determine the shear stress at point K, located at yK = 70 mm below the z centroidal axis.
