Pertaining to, or derived from, the dynamical action of water of a liquid; of or pertaining to water power. Hydrodynamic friction, friction produced by the viscosity of a liquid in motion.

An instrument to measure the velocity of a liquid current by the force of its impact.

hydric; as, hydrofluoric acid. Hydrofluoric acid (Chem.), a colorless, mobile, volatile liquid, HF, very corrosive in its action, and having a strong, pungent, suffocating odor. It is produced by the action of sulphuric acid on fluorite, and is usually collected as a solution in water. It attacks all silicates, as glas…

That branch of physics which treats of the mechanics of liquids, or of their laws of equilibrium and of motion.

Of or pertaining to hydrometallurgy; involving the use of liquid reagents in the treatment or reduction of ores. -- Hy`dro*met`al*lur"gic*al*ly, adv.

ental or moral power, etc.; not capable; as, incapable of holding a certain quantity of liquid; incapable of endurance, of comprehension, of perseverance, of reform, etc.

A foreign substance, either liquid or solid, usually of minute size, inclosed in the mass of a mineral.

Not capable of being reduced to the form of a liquid by pressure; -- said of any gas above its critical point; -- also particularly of oxygen, hydrogen, nitrogen, and carbon monoxide, formerly regarded as incapable of liquefaction at any temperature or pressure.

incapable of reduction in volume by pressure; -- formerly supposed to be a property of liquids. The incompressibility of water is not absolute. Rees.

by force or pressure into a smaller compass or volume; resisting compression; as, many liquids and solids appear to be almost incompressible. -- In`com*press"i*ble*ness, n.

Not condensable; incapable of being made more dense or compact, or reduced to liquid form.

To make thick or thicker; to thicken; especially, in pharmacy, to thicken (a liquid) by the mixture of another substance, or by evaporating the thinner parts.
