WebJul 23, 2024 · 9.3.1 A stationary hydraulic jump in a rectilinear channel. Downstream of a hydraulic control, the supercritical flow state is unstable. As a result it becomes turbulent and returns to a subcritical state (slower, … WebApr 10, 2024 · 3. Head Loss Formula: In Hydraulic Jump although momentum is conserved certain energy is lost. This Energy Loss is known as Head Loss and is given by the formula ╬öE = (yΓéé - yΓéü)┬│ / (4 * yΓéü * yΓéé) 4. Hydraulic Jump Length Equation: The Equation to determine the length of a hydraulic jump is found in several experiments.

Case C, the most dangerous condition, is … WebMar 5, 2024 · Another situation in which a hydraulic jump commonly forms is downstream of a change from a relatively steep channel slope, with which supercritical flow is …
WebApr 13, 2016 · 3. First a hydraulic jump is where fluid will transition from supercritical (having a Froude Number greater than one, to subcritical (having a Froude Number less than one). When the Froude number is near one, the jump is very weak and somewhat gradual such that you might not even be able to tell it is "jumping".
