In the previous paper, the optimum meridian profile of impeller and guidevane is able to obtain by blade-to-blade fluid loss calculated with diffusion factor. In this paper, considering the effect of annular fluid loss on optimum meridian profile of impeller and guidevane, the optimum profile is calculated by means of above method. The annular fluid loss is calculated by conventional annular friction loss coefficient. The effect of the annular friction loss coefficient on optimum meridian profile is mentioned in this paper. The annular fluid loss is caused by the meridian component of shearing stress of axisymmetric walls of hub and tip. In case of the component of tangential direction flow is large, in the calculation of annular fluid loss coefficient, the component of tangential direction flow is considered. The calculation of annular fluid loss has great influence on blade height of optimum impeller and guidevane meridian profile.
