摘要
对于非满流的圆管,作者根据用理论公式计算出来的充满度h/d与过水断面积A及水力半径R的对应数值,用回归分析方法得到三个有关h/d的比较简单又有相当精度的中间参数的关系式,应用这些关系式,仅用计算器就可以方便地对非满流圆管均匀流的水力计算进行数值求解.
For the circular pipes with partly full flow three functions which are simple in form but with enough calculated precision of intermediate parameters related to proportional depth h/d has been obtained via regression analysis of h/d and cross section A and hydraulic radius R calculated by theoretical formula. Applying this functions the approximate value in hydraulic calculation of uniform-flow in partly full circular pipe could be solved by a calculator.
