| 摘 要： | 基于水力学基本原理,对竖直管进水等径PVC三通管的局部损失进行了试验研究。分析了局部损失系数与入口雷诺数之间的相关关系。结果表明,随着雷诺数的增加,局部损失系数先减小再增大,呈良好的二次抛物线关系。

| Abstract: | Based on hydraulic principle,local loss parameter of diameter PVC pipe tee was studied and the relationship between local loss parameter and Reynolds number was analyzed.The results showed that local loss coefficient first decreased and then increased with the increase of the Reynolds number,between which there was a good second-degree parabola relation. |
