Homework Help: Pressure at the bottom of a container

  1. Jul 10, 2008 #1
    1. The problem statement, all variables and given/known data
    In an open glass container, 0.10 m of oil (rho=850 kg/m^3) floats on top of 0.20 m of water (1000 kg/m^3). What is the pressure at the bottom of the glass?


    2. Relevant equations

    (rho)(h)(g)= pressure at a depth of h


    3. The attempt at a solution

    The only thing I'm not sure of is: for the oil, should I consider h to be o.1 m, or the sum of both heights, making h 0.3?

    edit: I also know i have to add in 1 atmosphere at the end

    Each fluid gets its own "height". You'll find the sum of both pressures, not heights.
