Sluice gate flow equation
WebbSome authors prefer to describe a sluice gate as a half-model of a two-dimensional jet as shown in Figure 1.20, the bottom of the channel being the substitute for the plane of symmetry of the jet. Hence a discharge equation similar to Equation 1-67 is used to determine the free flow below the gate. This is Q=ceA& (8-8) Webb24 sep. 2024 · Total theoretical discharge through sluice gate with orifice [L/s] r : Height of roughness elements [m] R e 1 : Reynolds number at the initial depth S o : Flume bed slope V : The mean flow velocity [m/s] X : The distance from apron end to any point along bed material [m] y 1 : Initial depth of the hydraulic jump [m] y 2 :

By combining Bernoulli's equation and the continuity equation we get: Eq. 1 ho = Q2 / ( 2 g b2 h2 ) + h Eq. 2 Q2 = ho ( 2 g b2 h2 ) - h Eq. 3 Q = [ …
WebbOverflow gates are generally modeled with the standard weir equation: (6) Where: C = Weir flow coefficient, typical values will range from 2.6 to 4.0 depending upon the shape of the spillway crest (i.e., broad crested, ogee shaped, or sharp crested). Most overflow spillways tend to be sharp crested, so a value of 3.2 is typical. WebbBernoulli's equation provides the relationship between pressure, velocity and elevation along a streamline. It can be applied to solve simple problems, such as flow from a tank (free jets), flow under a sluice gate and flow through a nozzle. Applying Bernoulli's equation between points 1 and 2 as shown in the figures yields,
WebbThe mechanical energy equation is a fundamental equation of a 1-D mathematical model in Hydraulics and Engineering Fluid Mechanics.
