4. Hydraulic and geometric optimization criteria
This section presents a general method for classifying, comparing and optimizing propeller pumps, and the influence of various parameters on their hydraulic and geometric performance. It can also be used to determine the degree of refinement of an existing machine, and to specify quantitatively the various possibilities for improvement. It is a guide to choosing the most appropriate
torque for a given problem.
