In a huge oil tanker, salt water has flooded an oil tank to a depth of h2 = 4.50 m. On top of the water is a layer of oil h1 = 7.55 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.)
Salt water is poured into a U tube until it stands 0.250 m high in each arm. Oil is then added slowly to one arm until the salt water in the other arm stands 0.300 m high. The free surface of the oil then stands at 0.321 m high.
The level of oil in a storage tank buried in the ground can be found in much the same way as a dipstick is used to determine the oil level in an automobile crankcase. Suppose the ends of the cylindrical storage tank are radius of
) An oil tanker’s engines have broken down, and the wind is blowing the tanker straight toward a reef at a constant speed of 1.5 m/s (Fig.1). When the tanker is 500 m from the reef, the wind dies down just as the engineer gets
An oil tank in the shape of a right circular cylinder, with height 30 meters and a radius of 5 meters is two-thirds full of oil. How much work is required to pump all of the oil over the top of the tank? (The density of oil is 820
A U-shaped tube is filled mostly with water, but some vegetable oil has been added to both sides of the U tube. On the right side of the tube, the depth of oil is 5.00 cm . On the left side of the tube, the depth of the oil is
An oil tank is the shape of an inverted right circular cone with the pointed end down. The tank is 15 feet tall and is 12 feet in diameter at the top. At 1:00pm, the tank has oil 5 feet deep in it. Oil is pouring in at 5 cubic
an open tank contains a layer of oil floating on top of a layer of water (of density 1000 kg/m3) that is 3.0 m thick, as shown. What must be the thickness of the oil layer if the gauge pressure at the bottom of the tank is to be
