A large cylindrical container, with an inner diameter of 48cm, has a cylindrical, vertical tube which extrudes from one side. This tube has a inner diameter of 48mm. An unknown liquid reaches level A in the container, and Level B in the tube. The liquid supports a 20cm high column of oil in the tube between levels B and C. The density of the oil is 570 kg/m^3. Both the top of the container and the top of the tube are open to the air a. determine the mass of the oil b. determine the density of the unknown oil c. if you could seal the top to the container(with a piston of some kind) how much force would the piston need to produce so that the lliquid level at A and level B were at the same height?
