Constructing a compromise curve pump diameter - supplied power for the impeller pump

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.
