How to determine energy loss in hydraulic jump graphically?
Answers
ydraulic jump in a rectangular channel, also known as classical jump, is a natural phenomenon that occurs whenever flow changes from supercritical to subcritical flow. In this transition, the water surface rises abruptly, surface rollers are formed, intense mixing occurs, air is entrained, and often a large amount of energy is dissipated. In other words, a hydraulic jump happens when a higher velocity, v1, supercritical flow upstream is met by a subcritical downstream flow with a decreased velocity, v2, and sufficient depth. Numeric models created using the standard step method or HEC-RAS are used to track supercritical and subcritical flows to determine where in a specific reach a hydraulic jump will form.
There are common hydraulic jumps that occur in everyday situations such as during the use of a household sink.
the graph represents the following axis
x-velocity
y-frequency
So the graph of hydraulic is parabola
diagram so their is decreased curve that is energy loss
