Water for agricultural purposes were usually supplied either in a weir canal or through a hose flowing as an open-flow water system. To explore the possibility of utilizing these resources into energy this study was conducted to determine the performance of Tesla turbine using open flow water in a hose and in a weir canal. The performance of Tesla turbine was observed at different angles of inlet positioning from tangential or 00, 300, and 450 with respect to the flow of water. For a 10 minutes observation, results shows that the speed, power and efficiency of the machine is increasing as the time increases at all angles both for weir and flowing water in a hose. The relation of power and efficiency shows a straight line relationship at 00, 300, and 450 angles. The straight line result reveals that the power and efficiency of the machine is directly proportional to each other. Highest recorded Tesla turbine’s efficiency was at 00 angles of 34.42% for water flow using the hose and 29.45 % for rectangular weir. The result conclude that at angle 00 with respect to the flow of water is more efficient compare to 300, and 450 as it is (efficiency) decreases as the angle of inlet positioning increases with respect to the flow of water. © International Research Publication House.
