Sluice gate discharge from momentum balance
WebbThe gate is provided with a lifting mechanism so that the aperture beneath it may be set to any desired position. When closed, the aperture is sealed so that no flow can pass through the gate. In this experiment we measure the discharge under the gate and establish the effective coefficient of discharge. Webb15 okt. 2024 · The flow through the sluice gate can be categorized into free-surface and submerged flow, as shown in Figure 1a,b, respectively. For free-surface flow (Figure 1a), …

Webbof sluice gate discharge coefficient under free flow condition. Effects of factors on discharge coefficient were investigated. This new model can be used to predict the performance of sluice gates with different sizes under free -flow situations. 1. Introduction . Water resources management is closely related to the depletion of water resources. Webb8 feb. 2024 · Discharge from sluice gate flows is commonly calculated using the Torricelli outflow velocity, which is inaccurate and must be corrected by a discharge coefficient. Moreover, this approach commonly only considers the relative gate opening, without …

Introduction Sluice gates are widely used for controlling discharge and flow depth in many irrigational structural systems. Due to the practical importance of the sluice gate as a control and metering device, the prediction of the flow
Webbenergy-momentum equations in vertical sluice gates to predict a more applicable contraction coefficient instead of the typical 0.61 value. Although the results were satisfactory, it was shown that the estimated discharges have a 10% bias compared to the measured counterparts.
