A 30-ft-high, 1-ft-diameter pipe is welded to the top of a cubic container (3ft x 3ft x 3ft). The

container and pipe are filled with water at 20°C. Determine the pressure forces on the bottom and sides of the container.

I already know the solution to this problem, but I don't get how it conceptually makes sense. It says that the pressure at the bottom would be equal to 33ft*specific weight of water. However, I don't get this concept. It basically means the amount of water on top makes a difference to the pressure at the bottom, only the height. My questions is, if you change the diameter of that pipe to something ridiculously small, such as 1 micron, why would the pressure at the bottom remain unchanged????
