On the Discharge Coefficient of Radial Gate Outlets on Curved Practical Weir
It is found that the discharge coefficient of radial gate outlets on curved practical weir determined by the em-pirical method is relatively small.Therefore,based on the model test results of the overflow dam in Caculo-Cabaca Hy-dropower Station,the discharge coefficient of radial gate outlets on practical weir is analyzed with the least square fitting method.The relationship between the discharge coefficient and the relative opening height of the gate is obtained in sec-tions.It is shown that the fitted discharge coefficient is of high accuracy as the absolute error between the fitted and the measured values is 4.14%the maximum and 1.48%in the average.
