olm.calcite.calc_kappa4Franci(T_K, a_H, a_H2CO3s)[source]¶

Calculates kappa4 in the PWP equation using approach from Franci’s code.

Parameters:

T_K : float

temperature Kelvin

a_H : float

activity of hydrogen (mol/L)

a_H2CO3s : float

activity of carbonic acid (mol/L)

Returns:

kappa4 : float

constant kappa4 in the PWP equation (cm^4/mmol/s)
