Calculation of movement caused by a change in pressure

  1. Mar 25, 2015 #1
    1. The problem statement, all variables and given/known data
    Imagine you have an unflatable closed cube (z x z x z) which is connected to a chamber with a constant pressure of 6 bar (so the pressure in the box is also 6 bar). The box is hanging on a wire in a room in which the pressure is 1 bar. At t=0 a small part of the bottom of the cube opens (a x a x a , a < z). What is the force on the box and in what direction will it move?

    2. Relevant equations
    Sorry, but i have no idea. I tried using the standard PV = Cte and F=PA, but without any result so far

    3. The attempt at a solution

    unflatable = inflatable?
