水力半径
[流] hydraulic radius
- 通道长度与水力直径的比值为23，通道平均旋转半径与水力直径的比值为24。
The square channel has a length-to-hydraulic diameter ratio of 23. The mean rotating radius to the channel hydraulic diameter ratio was kept at a constant value of 24. - 冰盖的形成使得渠道的湿周增加，水力半径减小，输水阻力加大，致使渠道过流能力减小，影响渠道的冬季输水。
The ice cover in canal can increase wetted perimeter, reduce hydraulic radius and increase hydraulic resistance, which can diminish the water diversion capacity of canal. - 提出了U形渠道水力最佳断面的设计方法，并给出了确定U形渠道水力最佳断面底弧半径的计算公式。
The design method of U-shaped channel optimal hydraulic cross section and the calculation equation used to determine the bottom circle's radius of U-shaped channel is proposed in this paper.
