| 摘 要： | 根据微灌水力学原理,修正了微灌管道局部水头损失扩大系数,并对影响局部水头损失扩大系数的因素进行了敏感性分析。结果表明:当微灌管道出水口较少及进口端长度不等于出水口间距时,采用修正后的微灌管道局部水头损失扩大系数可以提高管道总水头损失的计算精度。

| Abstract: | Local head loss is an important part of the total head loss in pipeline of micro irrigation. According to the irrigation hydraulics principle, the expand coefficient of the local head loss in pipeline of micro irrigation is corrected, and carried a sensitivity analysis on the influence factor to the expand coefficient of the local head loss. Results show that:when the micro irrigation pipe outlet is less or the inlet is not equal to the outlet spacing, using the expand coefficient of the local head loss in micro irrigation pipe after correction can improve the calculation accuracy of the total head loss of pipeline. |
