Fluid mechanics - pressure, area, force question

  1. Jun 17, 2012 #1
    I have a question based on this little diagram I whipped up!


    Will the 25 PSI (generated by a pump) applied to the curved surface on the bottom of the piston exert a higher force upwards to oppose the downward force on top of the piston?

    A detailed explanation would be fantastic!

    You can integrate the vertical force components across the curved surface and find it equal to the flat one.
