Abstract


Piko hydro power plant construction using water turbines is still small. One of the challenges is that water turbines are not sold freely in the market, to get them people must order in advance so that the price of turbines becomes expensive. The purpose of this experimental study is to analyze the performance of blowers as turbines (BAT). The research results are known, that centrifugal blowers was successfully functioned as a water turbine. The smaller the size of the blower results in better performance. The performance of 2-inch blowers is superior compared to 2.5-inch, 3-inch and 4-inch blowers. The maximum power and efficiency of a 2-inch BAT is 583.02 Watt and 50.90% occurs at 14 m head, 8.34 L/s discharge and 800 rpm rotation. The mathematical equation of the BAT efficiency curve is y = 105.1x3 − 363.6x2 + 398.5x − 89.72. BAT applicative research in the community needs to be carried out by subsequent researchers to find out the challenges and ease of using centrifugal blowers as turbines.
