摘要
对于管路突然扩大的局部水头损失一般采用ｈｊ＝ξｖ２２ｇ计算，其中ξ＝（１－Ａ１Ａ２）２、在公式的理论推导中，此公式忽略了两断面间的沿程水头损失而导出来的。本文对两断面间的沿程水头损失进行了考虑，结合实验，对ｈｊ重新进行了推导计算，并进行了修正。
For the loss of head at sudden in the water pipe usually used a formula h j=ξv 22g to calculate, in which ξ=(1- A 1A 2) 2 In the calculation theory, this formula neglects the frictional head loss between two sections In this article the frictional head loss was considered, with the experiments, the h j have been calculated and amended
