The 1st report dealed with the fluid dynamical investigations of a model impeller of the centrifugal type hydraulic machinery, which has 4 vanes composed of the logarithmic spiral with the vane angle 30° and inner-outer radii ratio 0.5. In this paper the following model impellers classified into two groups were tested under the measurements of the head, flowing quantities and pressure distributions along the vane surfaces. The one has 4,6,8 and 12 vanes composed of logarithmic spiral with the vane angle 30° and inner-outer radii ratio 0.5,and the other has vane angle 30°, 50°, 70° and 90° with 6 vanes and radii ratio of 0.5. Moreover the measurements of the pressure distribution within the passage between the vanes were performed in a few cases in order to investigate the flow within the passage of the impeller.
