Homework Help: Pressure and density

  1. Oct 13, 2008 #1
    1. The problem statement, all variables and given/known data

    Your ear is a very sensitive pressure gauge. When you take a quick ride in a elevator
    going up or down in a building you notice a sensation in your ears when you travel only a
    few floors. A stronger effect is present in the rapid ascent or descent of an airplane - your
    ears notice. Assume that the area of your eardrum is 1.3 cm2. If you can just notice that
    funny feeling in your ears when you take a quick elevator ride from the top to the bottom
    of a ten-story building, what force increase are you able to notice on the eardrum?
    Convert you answer to pounds. Take each story of the building to be 14 feet high and
    presume the density of air is constant at D = 1.29 kg/m3.

    2. Relevant equations

    3. The attempt at a solution
