7.6.4.2.26. Incompressible_Ideal_Gas

Syntax: Density [{of} SpeciesName] = Incompressible_Ideal_Gas (P_Ref = p_ref | [T_Ref = t_ref] | R = r)
Scope: Aria Material
Summary: Incompressible ideal gas density
Description: $\rho = \frac{P_\text{ref} \mathit{MW}_\text{mix}}{R (T + T_\text{ref})}$

$\mathit{MW}_\text{mix}$ is the mixture molecular weight, $R$ the provided gas constant, and $T$ the temperature.
