H2O in ionomer
Extends from Gas (H2O gas).
Information
The thermodynamic data is set such that the density in equilibrium with H2O vapor will match the Springer et al. hydration curve [Springer1991] (see lambda_eq()) at λ = 14 and λ = 0. Otherwise, the properties are the same as H2O as an ideal gas.
For more information, please see the Characteristic package.
