【Abstract】 By using the mathematics knowledge such as least squares regression estimator, Gauss-Newton iteration method, together with the actual survey material, we get the common hydraulic formula when computing flow coefficient of radical gate of curve mould practical weir. Compared with the formula in use today, it is simple and accurate, so it is proper to be used in hydraulic calculation.更多还原
