Hydrostatic Forces Question_2

  1. Oct 7, 2007 #1
    1. The problem statement, all variables and given/known data

    a) Determine the horizontal and vertical forces acting on a wall sloped at angle, θ, to the horizontal seafloor as a function of z. Assume that the water is h deep and that atmospheric pressure acts everywhere. b) Determine the total resulting force and center of pressure.

    2. Relevant equations
    I really don't know what to use. Let's see:
    F = P_cg*A = (P_a + pgh_cg)A, where P_cg is the pressure at centre of gravity, P_a is the atmospheric pressure

    3. The attempt at a solution
    I really don't know how to approach this question, that's why i'm asking for help.

    Do you have a picture? Is this a seawall (sea on one side/air on the other), or is it a submerged wall?
