Consider the flow of water in a 10-m wide channel at a rate of 70 m3 /s and a flow depth of 0.5 m. The water now undergoes a hydraulic jump, and the flow depth after the jump is measured to be 4 m. Determine the mechanical power wasted during this jump, in MW

Water discharging into a 6 m wide rectangular horizontal channel from a sluice gate is observed to have undergone a hydraulic jump. If the flow depth and velocity before the jump are 0.5 m and 8 m/s, respectively, then which of the following statements is/are true? A Flow depth after the jump is 2.31 m. B Hydraulic jump formed is a weak jump. C Efficiency of jump is 65.6%. D Relative energy loss is 0.824.

Water is flowing in a 3 m wide rectangular channel. A hydraulic jump occurs and the flow upstream is 360 mm deep while the flow downstream from the jump is 1300 mm deep. A) Find the discharge flowing in the channel. B) Find the energy absorbed by the jump in kW. Please answer correctly

Problem 4 Water flows in a rectangular channel with channel width B = 4.0 (m). The specific energy diagram (SED) of this flow is given in the figure below. (y =0.2 m) (1) Estimate the channel discharge Q from the given SED. (2) If the water depth in the channel at a cross section is y₁ = 0.45 (m). The channel bottom is raised smoothly by Az = 0.2 (m). Determine if the flow will be "choked" by the raised step. If yes, estimate the "backed up” depth upstream, y₁. If not, what is the water depth y₂ above the step? y (m) 0.55 0.5 0.45 0.4 0.35 > 0.3 0.25 0.2 0.15 0.1 0.2 0.25 0.3 0.35 0.4 0.45 0.5 0.55 E (m)
