Information

This package may be used with the assumption of ideal gas or of constant specific volume, although it is more general than that.

Notes regarding the constants:

• b_v: The powers of p/T increase by row. The powers of T increase by column. If n_v[1] == -1, then the rows of b_v correspond to 1, B^*T, C^*T², D^*T³, …, where 1, B^*, C^*, and D^* are the first, second, third, and fourth coefficients in the volume-explicit virial equation of state [Dymond2002, pp. 1–2]. Currently, virial equations of state are supported up to the fourth coefficient (D^*). If additional terms are required, review and modify the definition of b_p.
• The defaults for b_v and n_v represent ideal gas.
