natasha543 Posted March 4, 2013 Share Posted March 4, 2013 Hi all, I'm trying to calculate A and B using the expression given in Helgeson(1969). The values I get seem to be quite off from the values given in the database and in Helgeson(1969). I think it's because my water density and dielectric constant calculations are wrong. Does anyone know what water densities and dielectric constants (as a function of temperature) were used to calculate A(T) and B(T) in thermo.dat? Also, I notice in thermo.dat that B(T) is tabulated without a factor of 10^8. Is this factored in by GWB or am I misunderstood in thinking that the coefficients B have a magnitude of 10^8? Many thanks, Natasha Quote Link to comment Share on other sites More sharing options...
