Help me to find out the hydrostatic force acting on an inclined immersed surface that is actually the diagonal of a 4mx3m rectangular tank filled with water. Given that the tank is 2m deep.
I know, F = Specific weight x Area x Depth of the center of gravity of the immersed surface from the free water surface.
But the problem is that I have no idea how to calculate that depth of the center of gravity of the immersed surface from the free water surface. Any help will be appreciated.
