In the previous paper the author developed the method to calculate hydrodynamically the performance characteristics of propellers in nonuniform flows by using the unsteady lifting surface theory. In the present investigation, applying this method to an example such as Dr. van Manen requested at the 10th I. T. T. C. to carry out tests of the given propeller and wake in various cavitation tunnels, he calculated the hydrodynamical velocities, forces and moments in open water and the nonuniform flow, and made partly clear the essential qualities of propulsion, and further found that existence of cavitation on the blades can be assumed theoretically.
