    This study investigates the performance characteristics of a locally designed Pelton turbine, focusing on the relationship between rotational speed, torque, and mechanical power output. Understanding these dynamics is crucial for optimizing turbine efficiency in various applications. Our experiments revealed that as the turbine’s rotational speed increased to 844 RPM, the torque decreased from 0.090 to 0.079 N·m, indicating a reduction in the efficiency of energy transfer from the water jets to the turbine buckets from 39% to 33%. This decline highlights the importance of maintaining an optimal speed range to maximize energy conversion. Furthermore, while power output initially increases with speed, operating the turbine beyond its optimal range can lead to diminishing returns due to mechanical and efficiency losses. These findings provide valuable insights for improving the design and operational strategies of Pelton turbines, ensuring enhanced performance and reliability
