Meridian hydrodynamic field data in an optimized domain depending of impeller type offers the perspective of results close to reality. Sections of the calculation are equal to the number of stream lines (11 lines of flow) which means doubling or even tripling them to the case of using the graphic-analytical method of tracing the hydrodynamic field. Choice of blade area in as many variations or options initially imposed is an additional possibility to optimize the blades. From the preliminary study it is known where D2 will be located on the output edge.
