A container is filled to a depth of 15.0 cm with water. On top of the water floats a 27.0 cm thick layer of oil with specific gravity 0.800. What is the absolute pressure at the bottom of the container.

Answer 1

(water density)*g*[0.15 + (0.8*0.27]
= 1000 kg/m^3*(9.8m/s^2)*0.366 m = ____ N/m^2 + Patm

Patm is atmospheric pressure, which must be added to the pressure caused by the weight of the two liquids.
