摘要
利用数学极值理论分析了管道无压流最大过流量、最大流速的发生工况,并建立了最大过流量、最大流速与管线纵坡、管径、管道糙率的关系表达式,为管道设计提供参考和依据。
The mathematics extreme theory is made use of analyzing the working condition of maximum discharge capability,maximum flow rate of free flow in pipeline,has put up the relational expression among maximum discharge capability,maximum flow rate and pipeline longitudinal slope,caliber,Roughness Coefficient,in order to provide the reference and the basis for channel design.
