Water tank pressure problem

  1. Sep 4, 2006 #1
    You have two closed water tanks. One tank is taller that allow pressure to build up from the shear weight of the fluid. And the other is alot shorter that is pressurized. If the pressure on the bottom of the tall tank was 5 psi and the pressure in the small tank was 5 psi. Would they both exert the same force? Or would the small tank have a stronger force on account of the tank being lower volume and have a high pressure.

    They would both exert the same pressure... so if you take a pipe and connect the two, no fluid would move between the two tanks. In other words, for a given element of fluid in the pipe of area A and thickness dx, the force would be PA - PA = 0, so it would not move.
