Slurry fluid level height

Agitation levels 3 and 5 characterize most chemical process industries solids-suspension applications and are typically used for dissolving solids. Agitators capable of scale levels of 3 will Suspend all the solids of design settling velocity completely off the vessel bottom Provide slurry uniformity to at least 1 /3 of fluid-batch height Be suitable for slurry draw-off at low exit-nozzle elevations. 

Agitation levels 6-8 characterize applications where the solids-suspension levels approach uniformity. Agitators capable of scale levels of 6-8 will a. Provide concentration uniformity of solids to 95% of the fluid-batch height. b. Be suitable for slurry drawoff up to 80% of fluid-batch height...
