摘要
针对目前多孔管沿程水头损失计算方法存在的问题,推导出了一个新的多孔管沿程水头损失近似计算公式。利用导出的公式,分析了多孔管沿程的压力变化,这无论是对喷、滴灌工程的规划设计,还是对多孔管水力特性的进一步研究都是有益的。
In this paper, a new approximate equation for friction loss along the pipelines with multiple outlet is presented, which is superior to the existing friction loss equations. The variations of pressure along the pipeline are analysed based on the new equation. The conclusion is useful both for the design of the sprinkle and drip irrigation and for the discussion of the hydraulic characteristics for multi-outlet pipelines.
