A manometer that is open to the atmosphere contains water, with a layer of oil floating on the water in one leg (see Figure P4.27). If the level of the water in the left leg is $1 \mathrm{~cm}$ above the center of the leg, the interface between the water and oil is $1 \mathrm{~cm}$ below the center in the right leg, and the oil layer on the right extends $2 \mathrm{~cm}$ above the center, what is the density of the oil?
