小球走迷宫 (2).png


小球走迷宫

       该展品展示伯努力流体力学原理。
       该展品各迷宫管之间气流流速的差正比于它们之间的气流压力差,当气流压力差调整至一定值时,小球便会按照迷宫的路径自由穿行。
       操作过程:①按下启动按钮,系统开始工作;②通过按钮操作调节迷宫管的气流速度,使小球在玻璃管中飘浮起来;③加大下一级玻璃管的气流速度,同时减小小球所在玻璃管的气流速度,小球便会按照迷宫路径一步步走下去,直到返回起点。设置时间一到,系统自动停止工作。


The small ball walks maze

       This exhibition displays Mr.Benuli's fluid mechanics principle.
       In this exhibition, the dispatch of the air's velocity of flow is directed ratio the dispatch of the air pressure among each maze tube. When the air pressure is adjusted to the certain value, the small ball will walks fluently according to the path of the maze.
       Operation process:①Press the start-up button, The system begin to work;②Through pushing the operating pole front and back, adjusts the air's velocity of flow in maze tube, so that the small ball can be floated in glass tube;③Enlarged the air's velocity of flow in next tube and let up it in the exact tube of the small ball exists at the same time, then the small ball will walk along the path of the maze step by step, until return the point of departure. Establishing time is on arriving, the system  will be ceased auto maticly.
