pub fn unconstrained_dx(
d_x_nacl: Result<f64, String>,
) -> Result<[f64; 2], String>Expand description
Unconstrained mole fraction derivatives for any property
The water mole fraction is ignored in the calculation; the salinity is determined from the NaCl mole fraction only (assuming that the mole fractions are normalized). So the derivative w.r.t. water mole fraction is identically zero.
§Arguments
d_x_nacl- NaCl mole fraction derivative, or an error
§Returns
The mole fraction derivatives with respect to both compounds, or an error.
