Comparison with current turbinesComparison with current turbinesTurbine 3:Type: ............. FrancisPower: ........... 190kWShaft type:...... HorizontalSpeed:............ 500rpmSpiral Case:..... SteelDraft tube:...... Conical
Turbine 1 and 2:Type: ............. FrancisPower: ........... 720kWShaft type:...... VerticalSpeed:............ 500rpmSpiral Case:..... SteelDraft tube:...... Conical
-Progressive increasing of the flow rate
-Improvement of the grid
-Probably nowadays only one turbine would be installed
