Notes:
Agitation and blending studies were made with solutions of Natrosol 250H, which were pseudoplastic fluids with nonconstant flow-behavior indexes. The published power number-Reynolds number correlation for pseudoplastic fluids having constant flow-behavior indexes is valid for Natrosol solutions. Published correlations for blend times in Newtonian fluids do not apply to Natrosol solutions; the blend times are ten to fifty times longer than with Newtonian fluids of the same apparent viscosity. Blend times are shortest in unbaffled vessels when a vortex is formed and correlate well with the vortex depths. Insertion of radial baffles always lengthened the blend time.
