Homework Help: Specific heat ratios of water, air, and related questions

  1. Nov 5, 2006 #1
    I've been working on a research project and I'm having difficulty with finding heat capacity values/heat capacity ratios. I have been getting 1.33 for the gamma value of steam, and 1.4 for air (at 300K). I was hoping someone could confirm these values.

    also, I have a question...let's say we have a sample of humid water, and i need to find the heat capacity ratio for that sample: would I do it by averaging the heat capacity ratios for steam and air relative to their % mass in the sample?


    thank you ahead of time.

    The Cp and Cv values of gases should be given in the back of any thermodynamics book for various temperatures and pressures.
