A Micro Hydro Pelton Turbine Prototype (Review of the effect of water debitand nozzle angle to rotation and pelton turbine power)

This research began when the writer conducted a field study to Curup Tenang Bedegung Waterfall, Tanjung Agung District, Muara Enim, South Sumatra. The CurupTenang Bedegung waterfall has the potential to build a micro-hydro Pelton turbine power plant. This study aims to see the flow rate andwater discharge. From this preliminary study, the researcher decided to carry out the design of a micro-hydro Pelton turbine prototype on a mini scale but has optimal rotation and power. In this study, the analyses of the effect of water dischargewere 20, 25, 30, 35, and 40 1/s and the nozzle angle was 50 degrees, 55 degrees, 60 degrees and 65 degrees toward rotation and Pelton turbine power. From the results obtained the higher the water discharge, the turbine rotation is increasing, the highest turbine rotation (691.3 rpm) achieved was at a water discharge of 40 l/s with nozzle angle of 50 degrees, the higher the water discharge will increase turbine power, the highest turbine power (15.89 watts) was obtained at a water discharge of 40 l/s with a 50 degrees of nozzle angle.
