2. Turbines

A turbine consists of a distributor, an impeller and a diffuser or aspirator. The distributor's role is to direct the liquid streams so that they reach the impeller at the right speed and in the right direction. The impeller is made up of buckets or blades; it transforms the kinetic and/or pressure energy of the water into mechanical energy. The diffuser or aspirator recovers the kinetic and/or gravitational energy that the fluid still possesses at the impeller outlet.

2.1 Action turbines

A turbine is said to act if the fluid pressure at the distributor outlet p _e (i.e. the pressure at the impeller inlet) and the pressure at the impeller outlet p _s are identical: p...
