You come across an open container that is filled with two liquids. since the two liquids have different densities, there is a distinct separation between them. water, which has a density of rho w = 1.00 × 10 3 kg/m 3 , fills the lower portion of the container to a depth of 0.221 m . the fluid that is floating on top of the water is 0.335 m deep. if the absolute pressure on the bottom of the container is 1.049 × 10 5 pa , what is the density, rho l , of the unknown fluid? the acceleration due to gravity is g = 9.81 m/s 2 and atmospheric pressure is p 0 = 1.013 × 10 5 pa .
