When designing the impeller pumps for aeronautical equipment the most essential characteristics are their mass and supplied power. Numerous publications have been devoted to developing the methods of constructing a compromise curve for determining the optimal parameters by means of LP-tau. Now it is necessary to find out to what extent this method is suitable for particular engineering calculations. In the previous research we noted that the application of LP-tau is justified for the low-flow pumps, but we also need to work out the ways to obtain reliable data while spending relatively little resources on its search. With this in view, we use a nondimensional generalized performance criterion that defines how much this computational point is suited for practical application.
