Ernest, my admittedly limited understanding of thermo properties leaves me to believe that specific heat already takes into consideration the different in density. In otherwords, the specific heat factor specifies how much heat it takes to raise a fixed amount of a material (cubic CC?) 1 degree. Therefore, the role density plays is already taken into account by determining the specific heat of the material. At least that is my understanding.
The units in the chart are given as Btu/lb/*F, so that is the amount of heat necessary to raise the temperature of certain mass. A higher density will allow more mass to pass by at the same flow rate. I don't think the 10% difference in density would change your conclusions (which I think are valid), but it would help explain the discrepancy in their performance numbers.
