The expanding hydraulic jump length was found to be 1.25 times of that corresponding of the free jump. Furthermore. the change in upstream and downstream depth leads to a change in the energy of an average 0.06 m [14.7].

Equations for hydraulic jump in horizontal rectangular channel (chaudhry. 1993; A hydraulic jump is a phenomenon in the science of hydraulics which is frequently observed in open channel flow such as rivers and spillways.when liquid at high velocity discharges into a zone of lower velocity. a rather abrupt rise occurs in the liquid surface.

#### Height Of The Standing Wave Or Hydraulic Jump:

Variables for hydraulic jump in a pipe back to calculation units shown in si for use in equations: The forming classical hydraulic jump in a horizontal bed. and wide rectangular open channel with a smooth bed has been studied extensively. [3.4.5. and 6]. The hydraulic jump lengths were divided by the water depth h1 in the supercritical flow region before the hydraulic jump phenomenon occurred to generalize the hydraulic jump lengths.

#### Q = V 1 Y 1 B = V 2 Y 2 B F 1 = V 1 / (G Y 1) 0.5 F 2 = V 2 / (G Y 2) 0.5.

This is the difference of water levels between two sections before and after the hydraulic jump. The stationary form is known as a hydraulic jump. and in the dynamic form. it is known as positive surge or hydraulic jump of translation. A hydraulic jump is a phenomenon in the science of hydraulics which is frequently observed in open channel flow such as rivers and spillways.when liquid at high velocity discharges into a zone of lower velocity. a rather abrupt rise occurs in the liquid surface.

#### Moreover. The Length Of Jump Increases And Y1 Decreases By Increasing Y2 As Indicated In Run 5.6.7.8. Included In Table 2.

L hj = y 2 (6.1+4.9s) where s= y4−y2 y2 (submergence ratio) y 2: This cannot be calculated analytically. Equation for the relative sequent depths of hydraulic jump in a trapezoidal cross section was derived by diskin (1961).

#### Subscript 2 Indicates Downstream Of Jump):

Table 4 shows the hydraulic jump length per unit flow and froude number measured at h 1. and figure 6 shows the hydraulic jump lengths per unit flow. There will always be frictional head loss across a hydraulic jump. due to the turbulence in the jump. Former equations for hydraulic jump occurrence in rectangular open channel ﬂ umes.

#### To Calculate Energy Loss In Hydraulic Jump. You Need Depth Of Point 2 (H 2) Depth Of Point 1 (H 1).

The position of the jump along the length of the trough (l) should remain constant over the entire experiment and is controlled by the weir at the end of the trough. The equation to determine the length of a hydraulic jump is found in several experiments. The rapidly flowing liquid is abruptly slowed and increases in height. converting some of the flows initial kinetic energy into.
