Lorsque le débit d'eau dans un tuyau d'incendie ou une canalisation est arrêté brusquement, par exemple en fermant rapidement une lance d'incendie, une onde de choc se produit lorsque l'eau en mouvement atteint l'extrémité du tuyau et rebondit. La hausse soudaine de pression ainsi produite se nomme coup de bélier. 3, record 1, French, - coup%20de%20b%C3%A9lier

Onda de presión muy rápida producida en un conducto, principalmente debida al manejo repentino de las válvulas o a un cambio súbito de régimen. 3, record 1, Spanish, - golpe%20de%20ariete
Record number: 1, Textual support number: 1 CONT
El cierre brusco de una tubería, el cortar la corriente, provoca un aumento instantáneo de la presión del agua. Esta zona de presión se propaga rápidamente (con la velocidad del sonido) en la tubería y puede hacerla estallar si tiene alguna junta o punto de menor resistencia. Este fenómeno, llamado golpe de ariete, reviste mucha importancia en las obras hidráulicas, especialmente en las presas hidroeléctricas. 4, record 1, Spanish, - golpe%20de%20ariete
