Select additional properties to be calculated (default: compute all available properties). You may want to disable some or all of these features to give a simpler output, particularly for temperature or pressure series.

Binary diffusivity will only be calculated for binary systems. The low-pressure diffusivity is calculated via the method of Fuller, et al (1969). High-pressure diffusivity is adjusted according to density and viscosity according to the method of Riazi and Whitson (1993).

Calculates the thermal conductivity for the system as a whole.

Calculates the viscosity for the system as a whole, using the selected units.

Calculates the fugacity coefficients (&Phi) for each species.

Computes the enthalpy and internal energy departure functions and total ΔH/ΔU for each state of a series calculation with respect to State #1. GasEOS returns:

1. the ideal-gas (P=0, or infinite volume) enthalpy and internal energy changes between T₁ and T_N.
2. the net enthalpy and internal energy departures to the ideal gas state at constant T from state #1 to state N, i.e.:
   (H₁ - H_ig) - (H_N - H_ig)
   
3. the total enthalpy and internal energy changes from state #1 to state N, calculated using the departure functions:
   ΔH_1-N = (H₁ - H_ig) + ΔH_ig(P=0) - (H_N - H_ig)
