我从这里有这个活塞动画：

另一个是水箱

\end{scope}
\draw[thick,->] (0,{-1.05*\r}) -- ++(0,{-0.3*\r}) node[right]{$v_e$};
\fill[fill=black] (0,0) circle (1pt);
\draw[dashed,|<->|] (0,0 ) -- node[above]{$R$} (210:\r);
\draw[|<->|] (4,{-\r}) --
node[fill=white,font=\footnotesize,inner ysep=2pt,inner xsep=0]{$h$}

\end{tikzpicture}
\end{tabular}
\end{document}
我的问题是：
如何组合它们左边是活塞，右边是水箱，所以当活塞完成 10 个循环时，水箱中的水将是空的。
您可以对水箱使用另一个代码，这只是我的一个例子。
