The article deals with the cylindrical tube mixers and the ones of a diffuser - confused type, in which the first liquid component flows into the inlet on the left, the second one- in the spray nozzle positioned orthogonally to the axis of the machine. The results of studies of the dependence of the specific rate of dissipation of turbulent kinetic energy on a variety of factors are given: the geometrical dimensions of the mixer, the density and molecular viscosity admitted to the unit components. The problem of the effect of scale on the hydrodynamic parametersis is stated and successfullysolved in the research.It has been established that, for the organization of the use of mixing of small-sizeunits and their systems instead of large tubular apparatus is more profitable.
