Hydraulics: Buoyancy - Concept and Example

An iceberg having a specific gravity of 0.92 is floating on salt water of sp.gr. 1.03 if the volume of ice above the water is 1000 cu.m what is the total volume of the ice. A block of wood 0.20 m thick is floating sea water. The specific gravity of wood is 0.65 while that of seawater is 1.03. Find the minimum area of a block which will support a man weighing 80 kg. An object weighs 4N in water and 5N in alcohol (SG 0.80). Assume unit weight of water is 9.79 kN/m^3 a. Volume of Object b. Weight of Object c. Density of Object
