In a huge oil tanker, salt water has flooded an oil tank to a depth of h2 = 4.85 m. On top of the water is a layer of oil h1 = 7.50 m deep, as in the cross-sectional view of the tank as shown in the figure. The oil has a density of 0.700 g/cm3. Find the pressure at the bottom of the tank. (Take 1,025 kg/m3 as the density of salt water.)

A closed and elevated vertical cylindrical tank with diameter 80 cm contains water to a depth of 0.900 m . A worker opens a circular hole with diameter 12 cm in the bottom of the tank. As the water drains from the tank, compressed air above the water in the tank maintains a gauge pressure of 5.00×103Pa at the surface of the water. Ignore any effects of viscosity ( ½w = 1000 kg=m3 ). a) (12 points) Just after the...
