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

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

28. 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
