In previous study, the optimum meridian profile of tandem impeller rotating at different speeds was obtained. As the first impeller was rotated at low speed rather than the second impeller, the performance of tandem impeller was improved in the calculation. In this study, the optimum meridian profile of tandem impeller and conventional impeller are compared at same specific speed. The specific speed was 1000 in the previous optimum calculation. For various specific speed calculation, the meridian profile was optimized using the meridian profile calculation result that was already optimized at another specific speed. In the process of this study, a lot of design parameters are needed. Therefore, in the first step some of design parameters are constant, the other design parameters are variable. In the second step, the constant design parameters are changed to variable, and the variable design parameters are changed to constant. As the result, the difference of meridian profile of tandem impeller and conventional impeller was obtained.
