Uniform flow (15.0 m³/s) occurs in a rectangular channel of width 3.50m at a normal depth of 3.80m. The Manning's n of the channel bed material is 0.025. A vertical sluice gate is placed across the channel with a get opening of 0.50m. (Ignore any energy losses associated with the gate). (a) What will be the depth of water behind the gate? (b) Determine the type of water surface profile behind the gate

A hydraulic Jump occurs in a trapezoidal channel having b=6ft, m=2, and Q=200cfs.  The flow depth just before the jump is 1 foot. What is the flow depth after the jump? What is the headloss due to the jump? What type of jump is it? What is the length of the jump?

The trapezoidal channel below must maintain a discharge of Q = 20 x SN (m3/s). You may assume that the channel slope is negligible. Use MS Excel spreadsheet to plot the specific energy curve and determine the critical depth Dc. Hint: You should first set up a column of normal depth D (m) ranging from 0 to SN, and then calculate the area (A), velocity (V), energy (E) and Froude number (Fr). ***SN=21

A rectangular channel is 4 m wide, and it reduces to 2 m through a hydraulic structure. Assuring the transition to be horizontal and the flow to be frictionless determine the water surface elevations upstream of the constriction when the specific energy at the constriction is 6 m. Assume choking occurs, hence critical flow equations are applicable. Note: Hand written solution is not allowed.

A partially open sluice gate discharges water into a rectangular channel. The tail water depth in the channel is 3m and Froude number is 1/2/2. If a free hydraulic jump is to be formed at downstream of the sluice gate after the vena contracta of the jet coming out from the sluice gate, the sluice gate opening should be (coefficient of contraction Cc = 0.9)

The spillway below discharges to a rectangular channel with 2 m width and 2.4 m³/s discharge. Find the energy loss in the hydraulic jump in meters. Hint: first, use the conservation of Specific Energy to find yı based on yo (assume negligible energy loss over the spillway). • Then, solve for y2 using Hydraulic Jump equations based on yı. Next, find energy loss using Hydraulic Jump equations based on y, and y2. Yo = 5 m-
