Hello Wolfram Community,

I am auditing a senior level HVAC Mechanical engineering course where the Psychometric Chart is heavily relied on to relate / calculate / approximate (in English units) Enthalpy in Btu per pound dry air, Dry Bulb Temperature, Wet Bulb Temperature, Relative Humidity, Humidity Ratio (pounds moisture per pound dry air), saturation temperature, cubic ft. of volume per pound of dry air.

If we can create a CDF to give calculate the same information and/or if Wolfram System Modeler can already perform this function, it will be well received in the HVAC world. And SI units will also be useful. Mathematica and System Modeler seems to me the ideal set of tools. See attached Psychometric chart jpeg. (Thank you in advance to the Wolfram Community where I can ask such questions).
