Question

Thermal, conductivity, density, viscosity, and prandtlnumbers of ethylene glycolwater mixtures

Answer 1

Thermal conductivity, density, and viscosity of ethylene glycol – water mixtures have been measured. The measurements have been performed in the temperature range from -−20°C to 180°C for thermal conductivity, from -−10°C to 150°C for density, and from – 10°C to 100°C for viscosity. Prandtl-Numbers calculated with the own experimental data and literature values of specific heat capacity are presented in dependence of temperature and concentration.

Answer 2

Explanation:

• Thermal Conductivity of Ethylene Glycol-Water Mixtures. For this research, thermal conductivity was measured with a concentric cylinder device in the temperature range of -20°C to 180°C, at saturation press
