In a barometer, if we replaced the mercury with alcohol and water?

  1. Sep 14, 2014 #1
    In a barometer, assuming bernoulie properties(incompressible fluid) if we replaced the mercury with alcohol and water why would the alcohol be able to be displaced further with pressure. It has a lower density that water 800kg/m^3 than water which has 1000kg/m3.

    What chemical properties or properties due to density would give us the result where alcohol can be moved up further when we apply the same pressure.

    What is the pressure at the bottom of a liquid column of a height h and a density ρ?
