Abstract The study aimed towards the design, fabrication, and testing of a hydrokinetic energy extraction system that utilized the speed of irrigation water in existing water canals installed by the local government and helped optimize the use of water by extending the utilization of irrigation water. The innovation in this study utilized crossflow turbine type employing blade profile for the turbine runner patterned to a NACA 000834 hydrofoil. The performance of the turbine such as theoretical water power, turbine internal, mechanical, belt and generator efficiencies were assessed. The theoretical water power available for extraction was computed at a value of 6928.53 Watts. The turbine has been found to run at 70.5 RPM with turbine internal and mechanical efficiencies are 44.57% and 71.57%, respectively. It was also observed belt efficiency of 69.74% and generator efficiency 74.45%. The system was able to produce 1152 watts of electrical power meant for small-scale power applications.
