对一端未封闭且装满水的容器而言,容器如何放置以及在容器的什么位置开口才会使得水射程最远?在文中针对这个问题建立物理模型,利用流体力学的伯努利方程和曲线运动给出了该问题的具体求解。研究的结果表明:只有当容器与地面成π-arccos(3~(1/2)/3)≈125.26°夹角放置,且在靠近容器底端的容器壁侧面开口,水的射程才会最远,且其最远射程等于83~(1/2)/9倍容器壁长。
For a container that is not closed at one end and filled with water, how the container is placed and where the container is open will make the water range furthest away. In this paper, we establish a physical model for this problem and use the Bernoulli equation of fluid mechanics and the curve Motion gives a concrete solution to the problem. The results show that the range of water can be farthest only when the angle between the container and the ground is π-arccos (3 ~ (1/2) / 3) ≈125.26 °, and the side of the container wall near the bottom of the container is open , And its farthest range is equal to 83 ~ (1/2) / 9 times the container wall length.
