The water pipeline’s fluid flow was utilized by the water turbine to spin the turbine runner, which ultimately produced electricity. Recently, researchers have focused more on developing a suitable water turbine design to utilize clean and renewable energy. This is because of the water delivery system’s inadequate capacity which typically results in the waste of excess potential energy. Rising pollution and other environmental threats have led to a dramatic increase in the usage of renewable energy sources in recent years. The efficiency of a pipeline water turbine with a 150-mm diameter was studied using simulation, and the findings of that study are presented in this work. The examination was done to evaluate each blade design’s effectiveness. To determine the best size, number, and angle of blades to be inserted in a water pipeline, the SolidWorks and ANSYS software were used to build and test the 2–6-blade turbines with 140-mm and 75-mm size turbines that are employing 2 types of angles, which are 90° and 45°. According to the data, a six-bladed turbine with blades that are 75 mm in diameter and at a 45° angle is the most suitable design since it produces the best outlet flowrate value from impact at the incoming water flow. The findings also revealed that, with the right blade angle and number, the system’s efficiency improved with increasing water flow rate. Because the size and shape of the blades generated are inappropriate, there will be turbulence formed. The efficiency, speed, and water flow of a turbine are all greatly affected by the number and design of its blades.
