Thermal conductivity: Approximately 0.0257 W/m Specific heat capacity: Approximately 1.006 kJ/kg This value is lower than that of pure water, leading to a slightly reduced rate of heat transfer in the cooling system.ĭensity: Approximately 1.225 kg/m³ (0.0765 lb/ft³) at sea level and 20☌ (68☏). Thermal conductivity: Approximately 0.41 W/m The viscosity of the mixture is higher than that of pure water, potentially affecting flow rates and pressure drops in the cooling system. The density is higher than that of pure water, which can slightly affect the flow characteristics and pumping requirements in a cooling system. This value is lower than that of pure water, meaning the mixture can absorb less heat per unit mass, but it still provides sufficient heat transfer capabilities for most cooling applications.ĭensity: Approximately 1060 kg/m³ (66.2 lb/ft³) at 20☌ (68☏). Specific heat capacity: Approximately 3.5 kJ/kg The boiling point can be further increased with a pressurized cooling system. This mixture offers excellent low-temperature protection, helping to prevent freezing in the cooling system.īoiling point: Around 106☌ (222.8☏) at atmospheric pressure.
Properties of a 50-50 ethylene glycol-water mixture:įreezing point: Approximately -37☌ (-34.6☏).The properties of this mixture and air are important for understanding their behavior under different conditions. The formulae can be easily pasted and integrated into other spreadsheets.Ī 50-50 ethylene glycol-water mixture is a common coolant used in various applications, such as automotive engines and HVAC systems. Properties calulated are:- Density, heat capacity, dynamic & kinematic viscosities, thermal conductivity and Prandtl number. Also the properties of air between -40C and +200C It will calculate certain properties of 50/50 Ethylene glycol and water between -30C and +120C. This sheet will be of interest to those who work with coolant-coolant or coolant-air heat exhchangers.
