| 摘 要： | 为了探明安装插入式灌水器的毛管局部水头损失计算方法及其在沿程水头损失中所占的比例，从水力学基本原理出发，分析了毛管局部水头损失与其影响因素之间的关系，推导出毛管局部水头损失及占沿程水头损失比例的计算公式，并进行了讨论分析。结果表明：毛管局部水头损失随着毛管内径的增大而减小，随着灌水器插头断面面积、灌水器流量和灌水器个数...

| Abstract: | In order to explore the calculation method for the lateral local head loss of insertion emitter and the proportion of the local head loss to frictional loss,based on the hydraulic principle,the relationship between local head loss and its effecting factors is analyzed and the calculation formula for the proportion of the local head loss to frictional loss is deduced.The study results show that the local head loss decreases with the increase of lateral diameter,while increases with the increase of the insert... |
