一、水流射程的理论表达式如图 1所示 ,容器内盛有某种液体 (例如图 1水 ) ,液面距容器底部的距离为 H,在容器侧壁某处开有一小孔a,小孔距液面距离为h,容器底部距参考平面的距离为 L,则小孔距参考平面的距离为 H + L - h.设容器中液体自小孔以速度 v喷出后的射程为 s.小孔的线 First, the theoretical expression of the water flow range shown in Figure 1, the container contains a liquid (such as Figure 1 water), the distance from the bottom of the container is H, a small hole in the side of the container opened a, The distance between the small hole and the liquid surface is h, the distance from the bottom of the container to the reference plane is L, and the distance between the small hole and the reference plane is H + L - h. The range after the liquid in the container is ejected from the small hole at the speed v is s. Line of holes
