【摘要】 从理论和实验两个方面分析了突扩管流动 .结果表明 ,在有压管流的突扩管段内 ,一方面沿程有机械能损失 ,另一方面由于下游管径的增大 ,造成动能减少和势能增加 ,受这两方面共同影响的测压管水头 ,无论何种工况 ,必定是增加的更多还原

【Abstract】 Theoretical and experimental study on the pipe flow with sudden enlargement pipe is made in this paper.The result shows that the piezometer tube water head of sudden enlargement pipe for a pipe flow is always increased with whatever operating mode, even though there are two contrary factors affecting it.更多还原
