A manometer that is open to the atmosphere contains water, with a layer of oil floating on the water in one leg (see Fig. 4-P27). If the level of the water in the left leg is 1 cm above the center of the leg, the interface between the water and oil is 1 cm below the center in the right leg, and the oil layer on the right extends 2 cm above the center, what is the density of the oil?
