Materials and compounds exhibit different hygroscopic properties, and this difference can lead to detrimental effects, such as stress concentration in composite materials. The volume of a particular material or compound is affected by ambient moisture and may be considered its coefficient of hygroscopic expansion (CHE) (also referred to as CME ...
The Hygroscopic cycle is a thermodynamic cycle converting thermal energy into mechanical power by the means of a steam turbine.It is similar to the Rankine cycle using water as the motive fluid but with the novelty of introducing salts and their hygroscopic properties for the condensation.
A hydroscope is any of several instruments related to water: One kind is an instrument for making observations below the surface of water, [1] such as a long tube fitted with various lenses arranged so that objects lying at the bottom can be reflected upon a screen on the deck of the ship that carries it. These are built with a large tire tube ...
Surface moisture: water held on the surface of coal particles or macerals; Hygroscopic moisture: water held by capillary action within the microfractures of the coal; Decomposition moisture: water held within the coal's decomposed organic compounds; Mineral moisture: water which comprises part of the crystal structure of hydrous silicates such ...
The following compounds are liquid at room temperature and are completely miscible with water; they are often used as solvents. Many of them are hygroscopic . Organic compounds
The healthiest bubbly water you can drink is plain, unsweetened, sparkling water or seltzer — just H2O plus CO2 — over those with sweeteners, flavorings, or other additives, says Zumpano.
Glycol-ether (DOT 3, 4, and 5.1) brake fluids are hygroscopic (water absorbing), which means they absorb moisture from the atmosphere under normal humidity levels. Non-hygroscopic fluids (e.g. silicone/DOT 5 and mineral oil based formulations), are hydrophobic, and can maintain an acceptable boiling point over the fluid's service life.
If biodiesel is indeed hygroscopic-- meaning that it has a strong tendency to pull water molecules out of the atmosphere -- there are serious implications in terms of its use, storage, etc., which would need to be addressed in the article. Currently, the problem of "Water contamination" is stated to arise because "Some of the water present is ...
