1. Collapse depth (or crush depth) is the submerged depth that a submarine cannot exceed without collapsing because of the surrounding water pressure. The collapse depth of modern submarines is not quite a kilometer (730 m). Assuming seawater to be incompressible (sp. gr. = 1.03), what is the crush depth pressure in N/m-and psi (Ib/in.)? Is the pressure you computed absolute or gauge pressure? 2. A storage tank 16 m * 6 m * 6 m2 is filled with water. Determine the force on the bottom and on each side. 3. A closed tank contains oil with a specific gravity 0.85. If the gauge pressure at a point 10 feet below the oil surface is 23.7 psi (lb/in.), determine the absolute pressure and gauge pressure (in psi) in the air space at the top of the oil surface. 4. A significant amount of mercury is poured into a U-tube with both ends open to the atmosphere. If water is poured into one leg of the U-tube until the water column is 3 feet above the mercury-water meniscus, what is the elevation difference between the mercury surfaces in the two legs? 5. water is flowing in pipe A and oil (sp. gr. = 0.822) is flowing in pipe B. If mercury is used as the manometer liquid, determine the pressure difference between A and B in psi. 32 in. 12 in. 20 in. Manometer liquid
