Laboratory Hydraulic Jumps

Hydraulic Jumps find application in open channel flow of fluid. When a liquid at high speed discharge into a zone of lower speed; a disrupted rise occurs on the surface of liquid. This rapidly flowing liquid is reduced and increase in height thereby converting some of flows initial kinetic energy through an increase in potential energy wherein a part of energy is lost through the turbulence to heat. However, when initial fluid speed is critical then no jump is possible. The stationery hydraulic jump is ideal for rapidly flowing water transitions into a stationary jump that allows slow movement of water. It also helps in controlling upstream water movement against water flowing downstream.
