A submarine is cruising at a specified depth from the water surface. The pressure exerted on the surface of the submarine by water is to be determined.Assumptions The variation of the density of water with depth is negligibleProperties The specific gravity of seawater is given to be SG = 1.03. The density of water at 32°F is 62.4 lbm/ft3Analysis The density of the seawater is obtained by multiplying its specific gravity by the density of water
