Because the water flow velocity distribution of the water passing cross section is uneven, the water passing cross section has the following characteristics:
1. the flow velocity of the middle area is greater than that of the edge area, the flow velocity of the edge area is symmetrical about the central axis and is distributed in a parabola shape, and the maximum flow velocity is generated on the axis;
