In this Report it has been discussed that (a) any sort of composition of converter circuit is suitable to normal or reverse operation and (b) any distribution of blade angle at leading or trailing edge over the width of flow path brings high efficiency. As the results of numerical calculation and theoretical consideration, it has been concluded that : (a) Pump→Turbine→Stator type is suitable to normal operation use and Pump→Stator→Turbine type to reverse operation, so far as only the single stage is concerned. (b) In order to guarantee that the efficiency of the whole flow path is equivalent to the value calculated on the design path, it is desirable that the condition of flow at the trailing edge of each member satisfies equation (rv_θ)_0=const., where r is radius, v_θ is circumferential component of absolute velocity at any point of trailing edge and suffix 0 represents the reference point.
