Density in water

  1. Oct 30, 2013 #1
    I would like to know if density is exactly the same everywhere in a disk full of water except at one part where there is gas. All are fixed: disk of water, and container of gas. I don't want the value of density just to know if density is exactly the same everywhere in disk of water. 2 cases:

    a/ disk is put on Earth, gravity is perpendiculary to the screen, diameter of disk is 10 km (theoretical study and I suppose gravity from Earth perfect)

    b/ disk is in space, it's size is 10000 km of diameter (all is fixed by external theoretical system)

    Gravitation & compressibility make it quite unlikely, although it depends how exact is your "exactly", as water compressibility is quite low.

    exactly is exactly the same value, precision at 1e-3000 if necessary

    Then the answer is "no".
