The propeller axial pump is comparable to the boat ducted propeller. the operating point of the propeller pump will be determined by the desired flow rate. This is not the thrust will be sought but the pressure variation.The propeller will be performed to ensure that at the desired rate, it generates the pressure difference equal to the head loss of the duct where the fluid flows.
Jet pumps used as thruster for submarines, jet ski or adapted on outboards are from this category. The diameter of the propeller is sometimes limited by the "draft boat" or by limiting the speed of the blade tip speed (cavitation).When you want to make a strong push with a small propeller there is the problem of pressure leakage at the tip of the blade but also the blade roots..
