In a special experiment, a stream of electricity was introduced into the tube (6) from an inner rope (or core) of a liquid with a viscosity of 3000 P under the operating conditions of 0.1 Qew of a blue dye it dissolved was surrounded by a ring of liquid which did not contain any dye. The volume flow of the dye-containing and the colorless liquid was in the ratio 4- ϊ 21. To test the effectiveness of the homogeneity improvement brought about by the mixing device, the composite flow was divided into three partial flows after passing through the mixing device, two of which were partial flows (hereinafter denoted by a and d) each V ^ - deo composed stream were the same and were taken from diamotrally opposite sides of the pipe that led the previous Ginigtcn Stroa.
