Homework Help: Hydrostatics - submerged lamina

  1. May 14, 2009 #1
    1. The problem statement, all variables and given/known data
    Calculate the depth below the water surface of the centre of pressure of the water pressure acting on the submerged triangular lamina, height 3m, base 2m and located at a depth of 1m below the surface.

    2. Relevant equations
    not entirely sure

    3. The attempt at a solution

    I found the centroid location at 2.5m from the surface, c= (2)(3)^3/36.. now i have no clue what to do. any tips?, I now that the center of pressure must be below this point
