using pressurized liquid to work
Working by using liquid under pressure, usually oil, to move parts of a machine.
Patrón de uso:
hydraulic [machine/system/part]
Error frecuente:
Learners sometimes think 'hydraulic' simply means 'water-powered' because of the 'hydro-' root. In modern engineering, hydraulic systems usually use oil or another special liquid, not plain water. Another mistake is using it as a noun (e.g. *"the hydraulic"*) instead of as an adjective modifying a noun (e.g. "the hydraulic system").
Sinónimos
fluid-powered (Broader and less specific; can refer to any fluid, while 'hydraulic' typically refers to liquid, especially oil.)
Antónimos
electric (Describes machines powered by electricity instead of pressurized liquid.)

relating to liquid flow behavior
About how water or other liquids move and act in science or engineering.
Patrón de uso:
hydraulic [properties/behavior/model/engineering]
Error frecuente:
Learners may confuse this scientific meaning with the more common mechanical sense and think it always involves machines. In environmental science, however, 'hydraulic' can describe natural systems, like rivers or groundwater, not just man-made equipment.
Sinónimos
fluid-flow (Informal technical description that focuses on movement of fluids in general; 'hydraulic' is the standard technical term in many fields.)
Antónimos
dry (Describes conditions without water or moisture, in contrast to situations involving moving water or other liquids.)
