Beattie-Bridgeman Real Gas Model

  1. Aug 3, 2007 #1
    I need to calculate the compressability of several gases as they are being added to a storage cylinder. I would like to use the Beattie-Bridgeman equation as described here.

    I need to be able to compute the Z factor (compressability) for a given gas at a given pressure.

    I am a bit new to this and need some help to work my way through this.

    So here is where I am at (far behind from what I can tell)

    P = pressure (this is what we are solving?)

    R = molar gas constant (I assume you look this up somewhere)

    T = temperature (From what I have read this is in K)

    V = volume of a mole of gas (The what?)

    A, B and c = empirical constants (I assume these are dirrerent for different gases. Is there a table somewhere?)

    I am dealing with O2, HE and Air (assuming .21 FO2 and .79 FN)

    Ususally I can figure out complex things like this is I get a shove in the right direction. Thanks

    Got the constants and figured out everything.
