A container is filled to a depth of 0.805m with water. On top of the water floats a 1.66m-thick layer of oil with density 700kg/m^3​​. What is the absolute pressure at the bottom of the container if the whole thing is placed in ordinary atmosphere at sea level? Give your answer in units of atm.

Answer #1

given
h1 = 0.805 m
h2 = 1.66 m
rho_oil = 700 kg/m^3

we know, rho_water = 1000 kg/m^3

Absolute pressure at the bottom = P_atm + rho_water*g*h1 + rho_oil*g*h2

= 1.013*10^5 + 1000*9.8*0.805 + 700*9.8*1.66

= 120577 Pa (or) 1.20577*10^5 Pa <<<<<<<<------Answer

    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 ρw=1.00×103 kg/m3, fills the lower portion of the container to a depth of 0.215 m. The fluid that is floating on top of the water is 0.342 m deep. If the absolute pressure on the bottom of the container is 1.049×105 Pa, what is the density, ρl, of...
