    Use gamma = 1.3 for the polytropic constant.

    Note: If you aren't using the cp and cv values to find this, ignore the above. If you are congratulate me for being clairvoyant.
    EDIT: It also depends on the blend of petrol and the fuel to air ratio (if you want to get technical and accurate)

    Gee thanks! but that's only the Cp value. what about the Cv value?
    and yes i have to calculate specific heat ratio
