Open flume turbine is a pico-hydro water turbine that can generate electricity up to 5 kW with low head. The open flume turbine typically designed using power specific speed, however Simpson proposed a method using discharge specific speed for pico-propeller turbine. This study compares the performance of pico-hydro open flume turbines designed with power specific speed and flow specific speed. The turbines are designed with 2.71m head with various flowrates. The flowrates are chosen so that the flow specific speeds are 140, 160, 180, and 200. Based on the result, the turbines designed using flow specific speed yield higher power output and efficiency at all designed flowrates.
