1. when the water flow passes the upper and lower surfaces of the wings 440, the lower surface flow rate is greater than the upper surface according to S = VT because the lower surface path is longer than the upper surface, and the water flow passes the upper and lower surfaces at the same time;
2. according to Bernoulli's theorem, the flow speed is increased and the static pressure of the fluid is reduced when the unpressurized ideal fluid flows along the flow pipe in a steady state; conversely, the flow velocity decreases and the static pressure of the fluid will increase; but the sum of the hydrostatic and hydrodynamic pressures of the fluid, referred to as the total pressure, remains constant at all times.
3. With the total pressure on the upper and lower surfaces of the wings 440 unchanged, the flow rate on the lower surface is greater than the flow rate on the upper surface, and the static pressure on the upper surface is greater than the static pressure on the lower surface, thereby creating a pressure differential and creating a downward pressure that causes the ballast to acquire a downward force.
