The Philippine Navy bought the latest 2300-tonned Kilo-Class Attack Submarine from Russia through the Philippine’s AFP Modernization Act. Russian Navy officers tried to show to the Philippine Navy officers what the capabilities of the submarine that they bought are. Before submerging, a Russian officer maximized the pressure inside the submarine and another officer saw and confirmed the pressure gauge with a value of 14.6 psig. The first test was in the submarine’s operational depth of 790 ft. At the second test, in its maximum operational depth of 980 ft. After the tests, the submarine resurfaced. A Kilo-Class submarine has a standard size of 70 x 10 x 6 meters. What are the absolute pressure at the (a) 1st and (b) 2nd tests? What are the hydrostatic pressure at the (3) 1st and (4) 2nd test? (5) Using its standard size, what is the buoyant force of a Kilo-Class submarine? (6) Is the buoyant force is enough to resurface the submarine?
