Homework Help: Pressure and Forces within Fluids

  1. Feb 21, 2009 #1
    Tank A

    |..........|
    |..h2o...|
    |..h2o...|
    |_h2o__|

    Tank B

    \.........../
    .\..h2o../
    ..\.h2o./
    ...\h2o/

    Tank C

    .../.....\
    ../.h2o.\
    ./..h2o..\
    /__h2o__\



    The three tanks shown above are filled with water to an equal depth. All the tanks have an equal height. Tank A has the middle surface area at the bottom, tank B the least and tank C the greatest.
    (Select T-True, F-False, G-Greater than, L-Less than, E-Equal to. If the first is F the second L and the rest G, enter
    FLGGGG).

    A) The water in tank C exerts an upward force on the sides of the tank.
    B) The pressure exerted on the bottom of tank C is greater than for the other tanks.
    C) The force due to the water on the bottom of tank C is .... the weight of the water in the tank.
    D) The force exerted by the water on the bottom of tank C is ... the force exerted by the water on the bottom of tank A
    E) The pressure at the bottom of tank B is ... the pressure at the bottom of tank C

    I can't seem to figure this one out. I've made several attempts and they are all wrong.

    Welcome to PF.

    What determines pressure?

    Pressure = Force/Area
