ocr: HYDROELECTRIC TURBINE YDROELECTRIC POWER STATIONS use water GENERATOR lturbines to extract energy from the powerful SHAFT flow ofwater through the base ofa dam. An efficient turbine extracts as much energy from the water Aow as possible. The Francis turbine shown here has a spiral-shaped inlet and guide vanes so that water hits the turbine blades with the minimum of energy- wasting turbulence. WATER INLET. WATER FLOW. GUIDE VANES.
