ENGINEERING APPLICATION Asubmarine has a total mass of including crew and equipment. The vessel consists of two parts, the pressure hull, which has a volume of and the ballast tanks, which have a volume of When the boat cruises on the surface, the ballast tanks are filled with air at atmospheric pressure; to cruise below the surface, seawater must be admitted into the tanks. (a) What fraction of the submarines volume is above the water surface when the tanks are filled with air? (b) How much water must be admitted into the tanks to give the submarine neutral buoyancy? Neglect the mass of any air in the tanks and use 1.025 as the specific gravity of seawater.
