Density pressure Temprature

  1. Apr 3, 2012 #1
    1. The problem statement, all variables and given/known data
    I have a grid with
    Surrounding density = rho
    Surrounding Temp = T
    Surrounding Pressure = P

    And I also have denser particles which over all have
    density = 10rho
    temp = 10T
    Pressure = P

    Now I want to average the densities, and have that as my new surrounding density with no particles .. But if i take the averages, I will get a different value for the pressure whiche doesnt make sense
    How would I take the average ?



    2. Relevant equations



    3. The attempt at a solution

    If the particles don't follow the same equation of state, how do you calculate the pressure for the combined gas? Or should you have the temperature of denser particles be 1/10 T?

    sorry yes T= 1/10 K
    and I think i worked it out, would this be the average density:

    (Volume of particle/total volume)*(10rho) + (Volume of surrounding/total volume)*rho = Average density
