ABSTRACT:
Blend times of liquids are determined by measuring the rate of change in dielectric loss of stirred liquid media. The blend times for partial or complete mixing may be determined by this method, for example, mixing is essentially complete when the dielectric loss becomes constant. Tracer materials may be added to liquid mixtures to alter dielectric properties so that changes in the dielectric loss are readily measurable. This method may also be used to determine the blend times for dissolution and mixing of solid or gaseous materials with liquids.
