对管路（突扩）局部损失系数的探讨

Study on Loss Coefficient of Sudden Enlargement Increaser

以圆形管路的突然扩大为例，对管路的局部水头损失系数ξ作了实验、分析和理论探讨，得出比较切合实际的计算公式。

Based on experimental analysis and theoretical discussion of local loss coefficient ξ in sudden enlargement circular pipe,a usable equation was suggested which had an additional correction coefficient.
