We handled the data valid to the circumference of the impeller that are related regarding optimizing the losses along the circumference and those that are related regarding the optimization to obtain an angular momentum free exit separately. The two data systems are interdependent, therefore a complete redesigning of the data may be required to obtain a suitable compromise. We gave a method to calculate the position of the radius widening out inside the impeller, which can be used for estimating the expected extent of the impact phenomena. Finally, we indicated the formulae to calculating blading geometry up to the practical requirements.
