Bake-out, in several areas of technology and fabrication, and in building construction, refers to the process of using high heat temperature (), and possibly vacuum, to remove volatile compounds from materials and objects before placing them into situations where the slow release of the same volatile compounds would contaminate the contents of a container or vessel, spoil a vacuum, or cause ...
A water heater that maintains desired temperature by turning the applied power on and off (as opposed to continuously varying electrical voltage or current) based on temperature feedback is an example application of bang–bang control. Although the applied power switches from one discrete state to another, the water temperature will remain ...
OpenTherm was founded in 1996 because multiple manufacturers needed a simple-to-use communicating system between room controller and boiler. It had to run, like the existing controllers, over the existing two wires, not polarity sensitive, without the use of batteries.
Barium iodide is an inorganic compound with the formula BaI 2. The compound exists as an anhydrous and a hydrate (BaI 2 (H 2 O) 2), both of which are white solids. When heated, hydrated barium iodide converts to the anhydrous salt. The hydrated form is freely soluble in water, ethanol, and acetone.
Barium fluoride is an inorganic compound with the formula Ba F 2.It is a colorless solid that occurs in nature as the rare mineral frankdicksonite. [9] Under standard conditions it adopts the fluorite structure and at high pressure the PbCl 2 structure. [10]
Gas stations are routine stops for most people, but they also present opportunities for criminals to take advantage of those who are unaware. Before you fill up your tank next time, it's important ...
A desoldering pump, colloquially known as a solder sucker, is a manually-operated device which is used to remove solder from a printed circuit board. There are two types: the plunger style and bulb style. [1] (An electrically-operated pump for this purpose would usually be called a vacuum pump.)
Benedict Cumberbatch recently participated in Variety’s “Know Their Lives” video series and shared some regret over his controversial role in Ben Stiller’s “Zoolander 2.” The “Doctor ...
