One of most controversial issues of modern tracer theory is the “complete mixing condition” because of its importance in evolution of hazardous solutes in natural flows. This condition named also as “Mixing length” measures the distance from pouring point when tracer particles have spread uniformly on cross section of stream. The point is that until now there is no rational, complete and easy to use formula to calculate it. Rather, this condition is evaluated mostly by means of empirical relationships; among them Ruthven's is one of current usage. Also there are statistical methods that applied by software packages allow to characterize this condition. However a new focus on this issue is important, because is necessary to tie together, generality, easiness and accuracy. This paper puts on discussion a thermodynamics method to understand when a tracer is in this remarkable condition. Herein it is developed the conditions when this method may be applied. It is shown also how the resulting formula is convergent with Ruthven's equation. An experimental demonstration is presented.
