Abstract
Decrease in viscosity of the coolant based on aqueous solution of ethylene glycol when electrolytes are introduced into its composition is being investigated. The versions with different mass fractions of ethylene glycol (23,6—46,4) and electrolyte concentrations (0,04—0,75 mol/kg) have been considered. A technique of the experiment and results of determination of characteristics of all types of coolants are presented. It has been found that the least viscosity is achieved with the minimum of electrolyte concentrations tested.
