Consider a large tank open to the air with a small opening near its bottom. Consider water flowing out of this tank through the opening. Why must the pressure near the surface and near the bottom be equal to atmopheric pressure?
As fluid elements travel down the tank, they will be accelerating. Therefore I don't see how one could apply the rule of thumb that the pressure between two interfaces should be equal.
