Gate hydraulics upstream depth
WebThe experiments used three different gate openings: w = 2.54, 3.81 and 5.08 cm (or 1, 1.5 and 2 inches). The discharge, Q, was adjusted to obtain desirable upstream flow depth, y1, and thus different y1/w. Twenty five distinct hydraulic conditions for the experiments is summarised in Table 1. For each of these WebThese parameters are; the upstream flow depth, the downstream water depth near the lip of the gate, the tailwater depth (in the submerged flow condition), the gate radius, the gate opening and the ...

WebE min = 1.5 y c, where y c is defined as the critical depth. The stream velocity at y c is defined as V c or critical velocity. A large flow height with V < V c is called sub-critical flow. In sub-critical flow, waves can travel upstream since the wave speed is greater than the … WebThe development of velocity profile away from the orifice and sluice gate is examined, and the effects of water depth are studied. The results of this study compare very well with other numerical and experimental studies, and provide a general understanding of the flow …
WebFor a given gate opening, the following steps summarize the solution process. The limiting upstream water-surface height for FW flow, y 1fw, is determined for the gate opening. The FW flow is assumed to just touch the gate lip, that is, y 2 = h g. The upstream water level required to produce the FW flow is computed from equation 108. WebHere, different models of gate position including vertical, deflection to upstream and downstream of the channel with respect to the vertical axis and also oblique position concerning the...
Webconstant upstream depth. Figure 2a also indicates that Y2 reaches about 0.1m at Y1 of 0.01m and speciic discharge (q) of 0.01m3/sec/m. Accordingly, igure 2b indicates that the Froude number at the upstream depth boosts as upstream depth declines that can be attributed to the increase in low velocity. On the other hand, an enhancement WebWhen the upstream water surface is greater than or equal to 1.25 times the height of the gate opening (with respect to the gates spillway crest), the gate flow equations are applied. When the upstream water surface is …
WebThe general equation for flow through an undershot gate can be derived from the Bernoulli equation and expressed as: where: Q = discharge (gate flow) C d = coefficient of discharge G o = vertical gate opening B = gate width g = gravitational constant H = a head term. …

Hubert Chanson, in Hydraulics of Open Channel Flow (Second Edition), 2004. Upstream and downstream controls. In subcritical flow a disturbance travelling at a celerity C can move upstream and downstream because the wave celerity C is larger than the flow velocity V (i.e. V/C<1).A control … boat rental lake ray hubbard texasWeb2. Adjust the gate height so the water level upstream of the gate, y 0, is just above the sixth pressure tap on the gate. 3.
