Topic: Hydro Static Pressure: 1. A submarine is designed to exert a pressure of 200,900 Pascal under the sea. Find the maximum depth where the submarine can make an operation. 2. A crew members attempt to escape from a sunken submarine that is lying on its side 100 m below seawater. The escape hatch area is 0.72m2 '2 a. Find the hydro static pressure at this depth. b. Find the force due to hydrostatic pressure applied on the escape hatch whose area is 0.72m2 ? c. If the pressure inside the submarine is 10.132x104 Pascal, nd the force exerted by this pressure. d. Since the force due to the pressure inside the submarine is less than the force due to hydrostatic pressure, find the force that they need to apply on the escape hatch in order to open it
