гидравлический удар
Резкое повышение или понижение давления движущейся жидкости при внезапном уменьшении или увеличении скорости потока
[ ГОСТ 26883-86]
гидравлический удар
Удар, создаваемый путем повышения или понижения гидромеханического давления в напорном трубопроводе, вызываемого изменением во времени скорости движения жидкости (газа) в сечении трубопровода.
[ ГОСТ 15528-86]
гидравлический удар
Повышение или понижение гидродинамического давления в напорном трубопроводе, вызванное резким изменением во времени скорости движения жидкости в каком-либо сечении трубопровода.
Примечание
Гидравлический удар имеет место при открытии или закрытии затворов, направляющих аппаратов турбин и т.п.
