Pressure and volume

  1. Mar 3, 2009 #1
    1. The problem statement, all variables and given/known data
    A diver rises quickly to the surface from a depth d. If she did not exhale the gas from her lungs before rising, by what factor would her lungs expand? Assume the temperature to be constant and the pressure in the lungs to match the pressure outside the diver’s body. The density of seawater is ρ. Express your answer in terms of d, ρ, g, and Patm (atmospheric pressure).


    2. Relevant equations

    P1V1=P2V2

    P2=P1 +pgd


    3. The attempt at a solution


    P2 (Patm) is a distance d below P1. SO,

    P1V1=P2V2
    Patm = P1 +pgd
    P1 = Patm - pgd
    (Patm - pgd)V1=PatmV2
    V1 = V2Patm / (1-pgd)

    is that right?

    No one can tell?
