Limescale is a hard, chalky deposit, consisting mainly of calcium carbonate (CaCO 3). It often builds up inside kettles , boilers , and pipework, especially that for hot water. It is also often found as a similar deposit on the inner surfaces of old pipes and other surfaces where hard water has flowed.
Cannula transfer using gas pressure. Mercury bubblers are largely similar in construction to oil bubblers. They usually have a longer body to prevent mercury from splashing out through the bubbler outlet, and the inlet connection usually has a sintered glass disc to prevent mercury from being sucked back into the inert gas system when refilling an evacuated vessel.
New applications are in inkjet systems where gas in the ink forms bubbles that degrade print quality, a degassing unit is placed prior to the print head to remove gas and prevent the buildup of bubbles keeping good jetting and print quality. The above three methods are used to remove all dissolved gases. Below are methods for more selective ...
A gas slug is a conglomerate of high pressure gas bubbles that forms within certain volcanoes, the agitation of which is a driving factor in Strombolian eruptions. They start out as small bubbles of gas inside of volcanic magma. [1] These accumulate into one large bubble, which starts to rise through the lava plume. Gas slugs also consist of ...
Nanobubbles can be formed by injecting any gas into a liquid. [ 10 ] [ 11 ] Because of their unique properties, they can interact with and affect physical, chemical, and biological processes. [ 12 ] They have been used in technology applications for industries such as wastewater, environmental engineering, agriculture, aquaculture, medicine and ...
Limescale build-up inside a pipe reduces both liquid flow and thermal conduction from the pipe, so will reduce thermal efficiency when used as a heat exchanger.. A descaling agent or chemical descaler is a liquid chemical substance used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters, and kettles.

A fluid inclusion is a bubble of liquid and/or gas that is trapped within a crystal. As minerals often form from a liquid or aqueous medium, tiny bubbles of that liquid can become trapped within the crystal, or along healed crystal fractures. These inclusions usually range in size from 0.01 mm to 1 mm and are only visible in detail by ...
