摘要
针对界限流量计算公式中存在的问题,采用现行成本计算和动态分析方法推导计算公式,并采用满宁公式计算水头损失,以适应设计中选用不同管材的要求.
Existing problems of limit flow rate formula are analyzed. A calculation formula is deduced from current method of costing and dynamic analysis. The loss of head is calculated by Manning formula, which could adapt the need of different materials.
