Título: Action and reaction hydraulic machines, what is the difference?
Descripción: López Jiménez, Petra Amparo; Pérez Sánchez, Modesto;
El presente objeto describe la diferencia entre las máquinas hidráulicas de acción y reacción a través de la definición del concepto de grado de reactividad y la utilización de este tipo de maquinaria en el conjunto de las máquinas hidráulicas, así como sus diferentes aplicaciones.

Descripción automática: In this video the difference between action and reaction hydraulic machines is explained. The degree of reaction, a parameter that relates to the ratio of static pressure in the pump pack and total head, is discussed. This ratio can be defined directly or indirectly, depending on velocity triangles and transformations inside the impeller.
Action machines, where water flow marks the turbine by direct impact on the impeller blade, are described. The Pelton turbine is given as an example, which produces energy through kinetic transformation. Reaction machines, where the direction of rotation does not coincide with the direction of entry and exit of water, are also explained. The Copland turbine is mentioned as a complete reaction machine that generates power by transforming flow into pressure inside the machine.
The video concludes by highlighting the importance of understanding the difference between action and reaction machines in hydraulic engineering, with examples provided to illustrate each type of machine.
