D a Vinci was the first to describe the hydraulic jump, and Bidone conducted classical experiments about 170 years ago . Scribd is the world's largest social reading and publishing site. It creates a flow with sufficient force to overcome the pressure caused by the load at the pump outlet. We made the implicit assumption that the flow coming from upstream had a combination of depth and velocity Experiment 5: Hydraulic Jump Key Concepts: Validity of the Equation, Hydraulic Jump Phenomenon Refer to: Roberson, Crowe & Elger, 7th ed.

Jump occurs , called as undular jump. Uses of Hydraulic Jump: The hydraulic jump is necessarily formed to reduce the energy of water while the discharge downfalls a spillway. However, the structures for riverbed protection downstream of movable weirs are designed using the criteria of fixed weirs in most cases, and these applications cause problems, such as scour and deformation of structures, due to misunderstanding the difference between PDF | Sluice gates are common hydraulic structures for controlling and regulating flow in open channels. Mohd Fadzil Faisae Faculty of Mechanical Engineering ffaisae@ump. • Due to mechanical action, the pump creates a partial vacuum at its inlet. ca . H. Based on wind directions and heavy wind blow, it changes its property and can be choppy and undular sometimes.
