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)

• A. (Ax̅/IG) + x̅
• B. (IG/Ax̅) - x̅
• C. (IG/x̅) - Ax̅
• D. (IG/Ax̅) + x̅

Answer: (D)
