【 摘 要 】

The blade is one of the main component of a turbine that is very interesting to study. The number of blades greatly affect the performance of a turbine. This research was carried out by varying the number of turbine blades in the horizontal flow and additional bulb in the pipe that used to break the fluid flow and direct the turbine blade. Variations in the number of turbine blades start at 4, 5, 6, 7, 8, with a water discharge of 5.3 1/s, 7.3 1/s, 8.5 1/s, 9.6 1/s and 11.4 1/s. The best results obtained on variations of blade 6 and discharge 11.4 1/s resulted in electrical power of 23.92 Watt with the voltage of 76.3 Volts and the current strength of 0.31 A.
