The depth of centre of pressure (h) for a vertically immersed surface from the liquid surface is given by (where IG = Moment of inertia of the immersed surface about horizontal axis through its centre of gravity, A = Area of immersed surface, and x = Depth of centre of gravity of the immersed surface from the liquid surface)

(IG/x̅) - Ax̅
(IG/Ax̅) + x̅
(IG/Ax̅) - x̅
(Ax̅/IG) + x̅
