Now in Brazil, most of the produced electric power and originating from hydroelectric that for your time are used of hydraulic turbines to transform the hydraulic energy (the pressure energy and the kinetic energy) of a flow of water, in mechanical energy and for your time in electric power. However they can also be used for generation of energy in small scale, for the isolated communities. In that way, this work looked for dimension and to manufacture a turbine of the type Francis in kindred scale of being used in small communities.
