Fluid Mechanics - Distance to Centroid

    1. The problem statement, all variables and given/known data

    http://i284.photobucket.com/albums/ll12/uradnky/fluid.jpg

    I'm asked to solve for the force on the projected plane surface and show where it is acting.
    This problem seems pretty easy, but with the dimensions given I can't find Lc, so I cant find dc to begin it.

    Is this just a simple trig problem that I'm missing? Or should I let the just let the angled surface above the circular plane be a variable that will cancel out later?

    If the angled surfaces above and below the circular window were equal in length, I think I could solve the problem. I am not sure if it is safe to assume this though.

    Thanks.

    EDIT : The DIAMETER of the circle is .45.





    2. Relevant equations

    F = [tex]\gamma[/tex] dc A
