摘要
基于孔口出流模型对底部有小孔的圆柱体容器中液体液面高度随时间的变化规律进行了实验研究,并通过计入液体表面张力引起的孔口收缩和流体黏滞力导致的能量损失对实验结果进行了理论分析,与实验结果一致.
Based on the orifice flow model, the variation of the liquid surface level with time was studied experimentally using a cylindrical container with a small orifice in the bottom. The theoretical analyses, when accounting of the contraction in the orifice induced by the liquid surface tension and the energy loss caused by the viscous force, were in good agreement with the experiment results.
