Pelton turbines Large heads (from 100 meter to 1800 meter) Relatively small flow rate Maximum of 6 nozzles Good efficiency over a vide range

Francis turbines Heads between 15 and 700 meter Medium Flow Rates Good efficiency =0.96 for modern machines

Kaplan turbines Low head (from 70 meter and down to 5 meter) Large flow rates The runner vanes can be governed Good efficiency over a vide range
