**HY8Hydraulic Jump Calculations XMS Wiki**

Condition for formation of hydraulic jump â€¢ When depth of flow is forced to change from a supercritical depth to a subcritical depth â€¢ Or Froude number decreases from greater than 1.0 to less than 1.0. â€¢ Jump will not occur when Froude number is less than 1.0 â€¢ Jump does not occur from subcritical to supercritical flow â€“ only vice versa. Figure 14.3 . 3 y1 â€“ supercritical flow y2... Predict if hydraulic jumps are to occur during flow, and calculate the fraction of energy dissipated during hydraulic jumps Learn how flow rates in open channels are measured using sluice gates and weirs. Introduction to Fluid Mechanics II 3 Open Channel Flow Classification of Open-Channel Flows Open-channel flows are characterized by the presence of a liquid-gas interface called thefree

**Fluvial Design Guide Chapter 7**

A hydraulic jump results when there is a conflict between upstream and downstream control. Example: upstream control induce supercritical flow and downstream control subcritical flow. => flow has to pass from one regime to another creating a hydraulic jump Significant turbulence and energy dissipation occurs in a hydraulic jump. 4 Applications of the Hydraulic Jump 1. Dissipation of energy in... relative to the horizontal, Lj is the length of the hydraulic jump measured from the toe of the hydraulic jump to the section where maximum surface level occurs. The hydraulic jump is located at the upstream of the channel

**HYDRODYNAMIC FORCES ON A SPILLWAY CAN WE CALCULATE**

Flow Properties of Horizontal Rectangular Channel Hydraulic Jumps Flow Rate Q (m 3 s-1) Channel Width B (m) Upstream Depth h 1 (m) Downstream Depth h 2 (m) Depth Ratio h 2 /h 1 Upstream... Calculate a) the force on the step. b) the head loss through the jump 10) A hydraulic jump occurs over a sill located in triangular channel with water flowing as â€¦

**Hydraulic jump 2178 Words Bartleby**

A hydraulic jump occurs when a two liquids of same fluid ( especially water) in an open channel which actually meets a sub critical flow of sufficient depth from a super critical flow with a high velocity then there is a abrupt increase in height of the downstream channel - this phenomenon of energy transfer is called as "Hydraulic Jump", in... A hydraulic jump occurs in a rectangular open channel. The water depths before and after the jump are 0.6 m and 1.5 m, respectively. Calculate the critical depth. The water depths before and after the jump are 0.6 m and 1.5 m, respectively.
