摘要
研究了微喷带沿程水头损失的确定方法,研究中设计了一套测试微喷带流量与压力的试验装置,提出了相应的测试方法和适合评价微喷带沿程水头损失的指标,通过对试验数据的回归分析得出了更加科学的微喷带沿程水头损失的经验计算公式。
In this paper,a determining method for frictional head loss of micro-sprinkling hose is put forward and equipment for testing micro-sprinkling hose flow and pressure is designed.Moreover,the corresponding test methods and evaluation index for frictional head loss are proposed and a more scientific empirical formula for calculating frictional head loss for micro-sprinkling hose is obtained through regression analysis of testing data.
