Reaction Turbines
Derive power from pressure drop across turbine
Totally immersed in water
Angular & linear motion converted to shaft power
Propeller, Francis, and Kaplan turbines
Impulse Turbines
Convert kinetic energy of water jet hitting buckets
No pressure drop across turbines
Pelton, Turgo, and crossflowturbines
