Real gas adiabatic equation

  1. Dec 10, 2011 #1
    Hey!
    Maybe anyone knows, how to get real gas adiabatic equation. It's not a big deal, when you need to get ideal gas equation, but I haven't got any ideas about real gas. I'm wondering maybe it's something with Van der Waals equation, but in my opinion it can't be like this :

    (p+a/V2)(V+b)[itex]\gamma[/itex] = constant


    So any ideas? It would be great, if you could show me detailed answer.

    I got an equation to solve for this, maybe anyone could help :

    n Cv dT + an/V + nRT logV/ logbn = 0

    How to get exact equation for adiabatic process from this ?

    The van der Vaal equation does not hold for all gases or all conditions it has limits.
