Hydrostatics U-tube again.

  1. Sep 20, 2011 #1
    1. The problem statement, all variables and given/known data
    U-tube has mercury of relative density 13.6. Column of light oil is poured into one limb. It is 15 cm tall and of relative density 0.78. A column of heavy oil is poured into the other limb so that it is level with the top of the light oil column. Find the height of the heavy oil column.

    2. Relevant equations

    3. The attempt at a solution

    Please find attatched.
    I must leave out my workings on converting Relative density to actual density.

    My problem is the Y value. 3 variables 2 equations.

    Ah I think I just realised, X = Y? Is that correct?
