Abstract: | In a discussion of blending and blend time, a distinction must be made among the terms: blending, mixing and agitation. Blending refers to the intermingling, of miscible fluids to produce some degree of uniformity. Mixing involves the production uniformity between materials that may not be miscible (For miscible liquids, mixing and blending are synonymous). Agitation is the most general term, involving the production of fluid motion for blending, mixing, heat transfer, mass transfer etc. |
