Homework Help: Pressure in Fliud

  1. Dec 8, 2008 #1
    1. The problem statement, all variables and given/known data

    A 0.50 meter thick layer of oil floats on a 1.20 meter thick layer of water. What is the pressure at the bottom of the water layer?

    2. Relevant equations

    p=p0 + (density)(gravity)(depth)

    3. The attempt at a solution

    I understand you treat the oil and water separately, as if they were both in separate tanks. Then simply add the results.

    The density of the oil is not given so I am not sure how to solve

    You will apparently need the density of oil. You could assume a rough value of 850 kg/m3 and 1000 for water for the purposes of the problem until you get clarification, or else solve it generally and give your answer as a function of ρ.
