Table obtained from Lange's Handbook of Chemistry, 10th ed. Specific gravity is referenced to water at 15.6 °C. See also "Typical Freezing and Boiling Points of Aqueous Solutions of DOWTHERM SR-1 and DOWTHERM-SR4000" (PDF). Dow Chemical. Archived from the original (PDF) on 27 September 2007
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
A 1:1 mix by mass has a specific heat capacity of about 3140 J/(kg·°C) (0.75 BTU/(lb·°F)), three quarters that of pure water, thus requiring increased flow rates in same-system comparisons with water. The mixture of ethylene glycol with water provides additional benefits to coolant and antifreeze solutions, such as preventing corrosion and ...
The choice of a heat transfer fluid is critical for system efficiency and longevity. Here are some commonly used fluids: Water: The most widely used due to its high heat capacity and thermal conductivity. Mono-ethylene glycol: Often used in a mixture with water to lower the freezing point for use in colder climates.
Vacuum distillation is often used in large industrial plants as an efficient way to remove salt from ocean water, in order to produce fresh water. This is known as desalination. The ocean water is placed under a vacuum to lower its boiling point and has a heat source applied, allowing the fresh water to boil off and be condensed.
Most antifreeze is made by mixing distilled water with additives and a base product, usually MEG (mono ethylene glycol) or MPG (mono propylene glycol). Ethylene glycol solutions first became available in 1926 and were marketed as "permanent antifreeze" since the higher boiling points provided advantages for summertime use as well as during cold ...
The higher boiling point of ethylene glycol compared to water allows the air to attain a higher temperature increasing the specific thrust. If the generated thrust is less than the aerodynamic drag of the ducting and radiator, then the arrangement serves to reduce the net aerodynamic drag of the radiator installation.
