Filling small compressed air bottle with a big one

  1. Nov 22, 2007 #1
    How can I figure the pressure in a 80 cubic inch tank at 0 psi being refilled
    with a 8000 cubic inch tank with a pressure of 3600 psi?

    - The total system volume before and after filling stays the same
    - The total mass of gas before and after filling stays the same
    - The pressures in the two vessels will equalise

    Does this help?
