Homework Help: Fluid mecanics problem

  1. Feb 24, 2008 #1
    An air bubble originating from a deep-sea diver has a radius of 1.8 mm at the depth of the diver. When the bubble reaches the surface of the water, it has a radius of 2.6 mm. Assume that the temperature of the air in the bubble remains constant. The acceleration of gravity is 9.81 m/s^2.

    A) Determine the depth of the diver. Answer in units of m.

    B) Determine the absolute pressure at this depth. Answer in units of Pa.

    P=rho(density)
    Pair=1.29 kg/m^3
    Psea water=1025 kg/m^3
    The volume of a sphere = (4/3)(Pi)(r^3)

    Any help with this would be greatly appreciated.
