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. 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. cheesecake philadelphia cupsWebbon a sluice gate mounted in lab flume of 12.5 m, 0.6 and 0.65 length, width and height, respectively, in the slope of 0.0002. Some equations of measuring the discharge from the sluice gate extracted from Energy equations and Momentum were calibrated using two metaheuristic algorithms of simulated annealing and ant colony. cheesecake photos
