mass_to_molar#

mass_to_molar(phase, MW='param.molecular_weight', rho='pore.density')[source]#

Calculates the molar density from the molecular weight and mass density

Parameters:

phase (OpenPNM Phase object) – The phase object to which this model is associated (i.e. attached). This controls the length of the calculated array(s), and also provides access to other necessary properties.
MW (str (dict key) or numeric) – Name of the dictionary key on phase containing the ndarray of molecular weight values, in units of [g/mol]. If a numerical value is passed (i.e. a scalar or ndarray) it gets used directly.
rho (str (dict key) or numeric) – Name of the dictionary key on phase containing the ndarray of mass density values, in units of [kg/m^3]. If a numerical value is passed (i.e. a scalar or ndarray) it gets used directly.

Returns:

value – A numpy ndrray containing molar density values [mol/m3]

Return type:

ndarray
