==Description==
'''Dosing''' generally applies to feeding [[chemicals]] or [[medicines]] in small [[quantities]] into a [[process]] fluid or to a living [[being]] at intervals or to atmosphere at intervals to give sufficient time for the chemical or medicine to [[react]] or show the results.
In the case of [[human being]]s or [[animals]] the word ''dose'' is generally used but in the case of inanimate objects the word dosing is used.
The word ''dosing'' is very commonly used by ''engineers'' in thermal [http://en.wikipedia.org/wiki/Power_stations power stations], in water treatment or in any industry where [[steam]] is being generated. Dosing procedures are also in vogue in textile and similar industries where chemical treatment is involved. In a power station treatment chemicals are injected or fed to [http://en.wikipedia.org/wiki/Boiler boiler] and also to feed and make up water under [[pressure]], but in small dosages or rate of injection. The feeding at all places is done by means of small capacity dosing [http://en.wikipedia.org/wiki/Pump pumps] specially designed for the [[duty]] demanded.
The feeding of [[chemicals]] in [[agriculture]] has also become common due to [[technology]] developments. However agricultural dosing is done by means of hand held [[pressure]] spray pumps or similar devices. [http://en.wikipedia.org/wiki/Dosing]
