Effects of geometrical attitude of runner blade on hydrodynamic performance of turbine are investigated experimentally and discussed in comparison with theoretical results. The best efficiency was obtained when the chord line of NACA0030 aerofoil was in contact with the pitch circle tangentially at 40% chord point. Comparing the calculated results with the measured data, the geometrical attitude of blade for the best runner efficiency is identical and the shape of time variation in runner torque is similar in both the calculation and the measurement, while quantitative agreement is still insufficient.
