A savanious horizontal water turbine is a type of micro-hydropower turbine that works in free-flowing water, such as a stream, canal, river, etc. In a current study, an experimental investigation of a single-stage savanious horizontal water turbine was carried out based on blade number, water depth, and flow rates. Twenty-seven experiments were performed, considering three factors and three levels. The effect of blade number, water depth, and flow rates on the performance parameters such as torque, rotational speed, and efficiency has been investigated experimentally and statistically. The results show that the overall performance of three, four, and five blades in torque, rotational speed, and efficiency decreases at higher water depths and flow rates. However, the performance of three, four, and five-blade savanious horizontal water turbines increased at optimum water depth and flow rates. Moreover, the overall performance of a four-blade single-stage savanious horizontal water turbine is higher than that of a three-blade and five-blade savanious horizontal water turbine. Furthermore, the ANOVA method reported that all input parameters significantly affect the output response of the single-stage savanious horizontal water turbine.
