HYDROSTATIC, HYDROSTATICAL

a.[Gr. water, and static, standing or settling. ] Relating to the science of weighing fluids, or hydrostatics.

 

HYDROSTATICALLY

adv. According to hydrostatics, or to hydrostatic principles.

 

HYDROSTATICS

n.The science which treats of the weight, motion, and equilibriums of fluids, or of the specific gravity and other properties of fluids, particularly of water. Hydrostatics is that branch of the science of hydrodynamics which treats of the properties of fluids at rest.

 

Webster's 1913 Dictionary

HYDROSTATIC; HYDROSTATICAL

Hy `dro *stat "ic, Hy `dro *stat "ic *al, a. Etym: [Hydro-, 1 + Gr. hydrostatique. See Static. ]

 

Defn: Of or relating to hydrostatics; pertaining to, or in accordance with, the principles of the equilibrium of fluids. The first discovery made in hydrostatics since the time of Archimedes is due to Stevinus. Hallam.Hydrostatic balance, a balance for weighing substances in water, for the purpose of ascertaining their specific gravities. -- Hydrostatic bed, a water bed. -- Hydrostatic bellows, an apparatus consisting of a water-tight bellowslike case with a long, upright tube, into which water may be poured to illustrate the hydrostatic paradox. -- Hydrostatic paradox, the proposition in hydrostatics that any quantity of water, however small, may be made to counterbalance any weight, however great; or the law of the equality of pressure of fluids in all directions. -- Hydrostatic press, a machine in which great force, with slow motion, is communicated to a large plunger by means of water forced into the cylinder in which it moves, by a forcing pump of small diameter, to which the power is applied, the principle involved being the same as in the hydrostatic bellows. Also called hydraulic press, and Bramah press. In the illustration, a is a pump with a small plunger b, which forces the water into the cylinder c, thus driving upward the large plunder d, which performs the reduced work, such as compressing cotton bales, etc.

Defn: One who is versed or skilled in hydrostatics. [R.]

 

HYDROSTATICS

Hy `dro *stat "ics, n. Etym: [Cf. F. hydrostatique.] (Physics )

 

Defn: The branch of science which relates to the pressure and equilibrium of nonelastic fluids, as water, mercury, etc. ; the principles of statics applied to water and other liquids.
