A Vertical Pipe, Closed at the Bottom End, Is Filled $0.800 \times 10^{3} \mathrm{~kg} / \mathrm{m}^{3}$

Short Answer

A vertical pipe, closed at the bottom end, is filled to a depth of 1.00 m with water and then an amount of oil of density $0.800 \times 10^{3} \mathrm{~kg} / \mathrm{m}^{3}$ is added to make the total depth 2.00 m. The oil and water don't mix with the oil floating on top of the water. What is the increase in pressure at the bottom end of the pipe as a result of adding the fluids?
