Can equation 6 be applied directly to multi-component mixture if I know the pur component thermal conductivities without using equation 7? If not, how can I apply equation 7?

ABSTRACT A local composition model for multicomponent, liquid mixture thermal conductivity has been developed and tested. Only binary equilibrium thermodynamic information is used in the model to obtain local compositions. No mixture thermal conductivity data are required and no adjustable parameters are used. Predictions based on this model agreed, within experimental uncertainty, with the experimental results for eighteen different binary mixtures at 1 atm and various temperatures. An average absolute percent deviation from experiment of 1.0% was obtained over the entire composition range for the eighteen systems. The maximum deviation at any of the tested compositions was 3.5%. Thermal conductivities for ternary systems have also been computed.
