The infusion rate of a slug of tracer into an anchor agitated 100-liter batch mixer was characterized by a decay rate constant.
This constant was then used to define a dimensionless mixing-rate number which was related to the stirrer Reynolds number.
This correlationship allows the calculation of time or rotational speed needed to achieve any desired degree of uniformity
of the mixture.99mTc was used as radiotracer and the mixing process was followed by a scintillation Nal(Tl) counter situated on the reactor
wall near the injection point.
