Experimental study of small hydro turbine propeller performance with a variety of blade angles of attack

The availability of non-renewable energy has recently been running low and so impacts electrical energy. Renewable is converted from natural sources to kinetic Double Propeller Water Turbine a water turbine that suitable be applied using small flow head. This research development previous by changing the degree inclination blade angle on turbine, which used determine changes in power efficiency at various speeds. results showed rotation’s performance was directly proportional slope angle. optimum attack hydro affected lift force ability capture power. At lowest angle, 20 degrees, highest rotational speed obtained with value 335 rpm. generates most significant 20o, 4.81 watts, 24%. affects turbine.
