Homework Help: Centibarrer equation

  1. Jun 17, 2007 #1
    1. The problem statement, all variables and given/known data
    I have an equation that tells you the number of cubic cm of gas permeable
    through an item. But I'm not getting a proper answer.
    what does Hg stand for and what is its value. does anyone know the proper values for this equation and how to solve.
    the values I have are 1 square cm, .238125 cm thick, time is one second.
    I think Hg is to be the partial pressure difference across the membrane.
    2. Relevant equations

    3. The attempt at a solution

    I've never heard of the centibarrer equation before but cm Hg probably means centimeters of mercury which is a pressure. Hope that helps.
