Note that the properties may vary depending on the temperature, pressure, and other factors, so always refer to manufacturer data or reliable sources for accurate information. These properties of the 50-50 ethylene glycol-water mixture and air are important for designing and analyzing various thermal and fluid systems, such as cooling systems, heat exchangers, and HVAC equipment. Thermal conductivity: Approximately 0.0257 W/m Specific heat capacity: Approximately 1.006 kJ/kg Air - Dynamic and Kinematic Viscosity Online calculator, figures and tables with dynamic (absolute) and kinematic viscosity for air at temperatures ranging -100 to 1600☌ (-150 to 2900☏) and at pressures ranging 1 to 10 000 bara (14.5 - 145000 psia) - SI and Imperial Units. The speeds of the drive shaft in revolutions per. Absolute viscosity of steam at pressure ranging 1 - 10000 psia. 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☏). the density of air-free water at 20C and a pressure of 1 atm. 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. Atmospheric and Vacuum Residues by High Temperature Gas Chromatography. At sea level and at 15 C, air has a density of approximately 1.225 kg/m 3 (0.001225 g/cm 3, 0.0023769 slug/ft 3, 0.0765 lbm/ft 3) according to ISA (International Standard Atmosphere). viscosity was used to correlate the viscosity data. It also changes with variation in temperature or humidity. This mixture offers excellent low-temperature protection, helping to prevent freezing in the cooling system.īoiling point: Around 106☌ (222.8☏) at atmospheric pressure. Air density, like air pressure, decreases with increasing altitude. 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.
