Design constants for impeller outlet dimensions, psi and phi, were examined and derived based on loss analysis for the impeller and volute which was originally developed for performance and efficiency conversion. The design constants were calculated using outlet dimensions of the impellers which were designed for the requirement of the same flow rate and speed of rotation but with various pump heads and outlet angles giving minimum hydraulic and disc friction losses. The investigated design constants coincide relatively well with the conventional values given, for example, by Stepanoff in the range of blade outlet angle of about 20°. Furthermore, the results provide good suggestions for the values of psi and phi to be chosen for the outlet angles larger than 20°.
