Text: "The mechanical subdivision of a bulk liquid. Other terms are also applied to this process, although the terminology is not standardized. Spraying usually implies the production of coarse drops (100-1000u). Sprinkling suggests very coarse drops(greater than 1000u). Misting is often applied to the production of fine drops (10-100u), and nebulizing to the production of very fine drops (under 10u), usually used in inhalation aerosol therapy. Atomization may be used to subdivide meltable solids, such as certain metals."
