It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.20 GPa). As one goes deeper and deeper in the ocean, the pressure increases by 1.0*10^4 Pa for every meter below the surface.

If a diver goes down 33.0 m (a bit over 100 ft) in the ocean, by how much does each cubic centimeter of her blood change in volume?

This is the work that I have, I think that I may be converting something wrong somewhere...??

(delta)v= (delta)P/Bulk Modulus *V

delta)v=[1.0*10^4]/[2.2*10^9] *33
=1.5*10^-4

they want the answer in cm^3

  • Physics -

    That is m^3, so change it by multiplying by 10^6 cm^3/m^3

  • Physics -

    I did that and I'm still getting a wrong answer...

    Is it possible that my calculations are wrong somewhere else?? I'm at a loss...

  • Physics -

    It is -1.5* 10^-4
