design of propeller turbines for pico hydro
Singh and Nestmann 2009 designed and tested a five blade propeller turbine that produced 810 W 739 hydraulic efficiency at 900 rpm while operating under a head of 175 m and flow rate of 0064 m3s 3. The implementation of this stand-alone system is chosen due to its cost-effectiveness and robustness in producing electricity under low head conditions.
