pressure	the phase pressure \(\mathrm{[Pa]}\)

henry()

template<class Scalar >

static Scalar Dumux::BinaryCoeff::H2O_N2::henry ( Scalar  temperature )

inlinestatic

Henry coefficient \(\mathrm{[Pa]}\) for molecular nitrogen in liquid water.

Parameters

temperature

the temperature \(\mathrm{[K]}\)

liquidDiffCoeff()

template<class Scalar >

static Scalar Dumux::BinaryCoeff::H2O_N2::liquidDiffCoeff ( Scalar  temperature, Scalar  pressure  )

inlinestatic

Diffusion coefficient \(\mathrm{[m^2/s]}\) for molecular nitrogen in liquid water.

Parameters

temperature	the temperature \(\mathrm{[K]}\)
pressure	the phase pressure \(\mathrm{[Pa]}\)

The empirical equations for estimating the diffusion coefficient in infinite solution which are presented in Reid, 1987 all show a linear dependency on temperature. We thus simply scale the experimentally obtained diffusion coefficient of Ferrell and Himmelblau by the temperature.
