In the paper presents the calculated optimal values of the baric thermal conductivity coefficients corresponding to the minimum of the quadratic functional in comparison with the baric dependences of aqueous solutions of ethylene glycol and electrolytes in the cooling systems of marine internal combustion engines. For the pressure dependences of electrolyte solutions, an equation was obtained that makes it possible to calculate the thermal conductivity of mixed solutions at any pressure with an average error of 1.2%. Scientific interest lies in the study of the nature of the dependence of the baric coefficients of thermal conductivity of mixed electrolyte solutions on temperature when using the latter along with ethylene glycol coolants
Pressure in the cooling system, thermal conductivity of mixed electrolyte solutions, baric coefficient, concentration of an aqueous solution of a cooling liquid, concentrations of binary solutions
