Svedberg in first years of 1900, the approximate number 1.54 is considered as a mean number of colloidal particles moving randomly in a reticule, but it is actually a pattern property of spatial and time in diffusion processes. This paper presents how the introduction of this number in Poissons distribution allows to describe particle dynamics not only in the so-called “diffusive period”(after Complete Mixing condition), but also in early period of plume evolution (Convective Period) in stream transport processes. An experimental proof of this statement is discussed to show how last period is Gaussian too, against current picture of mass transport.
