摘要
用于 U形渠道量水的抛物线形喉口式量水槽原流量公式为隐函数形式 ,针对其使用不便的现状 ,通过理论分析推导出了显函数形式的量水槽流量公式 ,计算结果与原流量公式比较相对误差值 <0 .5%
The original flow rate formula of parobolic throat flume used for U shaped channel is implicit function and is not convenient for calculation in irrigation districts.An simplified formula is developed in this paper,with a difference between results calculated with the original formula and the new formula being less than 0.5%.
