Table 8-3-1

This document contains a table providing thermal properties of various glycol mixtures including monoethylene glycol, 1,2-propylene glycol, and their mixtures with water at different concentrations and temperatures. For each substance and concentration, the table lists temperature, density, specific heat, thermal conductivity, dynamic viscosity, and kinematic viscosity at temperatures ranging from -40 to 100 degrees Celsius. All thermal properties generally increase with temperature except for density and dynamic viscosity, which decrease with increasing temperature.
