Determines some physical and thermodynamic properties of air at different altitudes. Uses the international units system (SI) and considers dry air. Altitude range permitted is from -5,000 to 20,000 meters; in this range air is considered ideal gas.
Thermodynamics Program. Given temperature, pressure and critical properties for a pure substance (gas or saturated condition); this calculates: compressibility factor “z”, volume, transience, and residual properties. PR and RK EOS are used.
