This study has been employed experimentally towards Savonius water turbine by using Myring equation for n=1. This work will be varied to overlap ratio of 0, 0.05, 0.1, 0.15, 0.2, 0.25 and 0.3. The overlap ratio of 0 can be called as the conventional turbine using half circle. The experiment is tested in flume tank by 1.1 m of wide and 0.8 m of height and the water velocity 0.22 m/s. The turbine have 0.4 m of height and 0.4 of diameter. This work will be calculated the torque coefficient and the power coefficient. The power coefficient is called the performance coefficient. The results indicated that the best performance coefficient has improved in about 62.83 % at overlap ratio of 0.2.
