用动能经济方法确定排灌泵站的经济管径

Determining Economic Pipe Diameter of Irrigation and Drainage Pumping Station With Kinetic Energy Economy Method

根据动能经济方法的经济管径公式,选定各项参数,对常用的管材进行了经济管径的计算,给出了不同管材的经济管径与设计流量、年运行小时数的关系。

According to the formula of kinetic energy economy method,we have selected the parameters, calculated economic diameter of different common material pipes and given out the relationship among economic diameter,design discharge and runtime for different material pipes.
