 I'm still working on these two spread sheets, but if you would like to take a look at my progress, you may download them at these links.

ThermDynamicDensity Spread Sheet - Formulas for Specific Density, Heat Density, Volumetric Heat Density, Conductance and conversions between the various system units.

 BTU Calculator  - Examines Costs and Design of Thermal Collection, Storage, and Heat Exchange

I can't guarantee that the formulas are correct, but you may find them useful if you too are trying to work through these calculations.  My goal is to create a spread sheet that will offer a systematic approach, and all the calculations required in the design of a year round thermally balanced (70F +/- 10F) aquaponic green house system.
