Hydrostatical   Listen
adjective
Hydrostatical, Hydrostatic  adj.  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."
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.

"Hydrostatical" Quotes from Famous Books



... equilibrium of pressure in fluids, as exhibited in the well known 'hydrostatic paradox.' In his patent of 1785, in which he no longer describes himself as Cabinet maker, but 'Engine maker' of Piccadilly, he indicated many inventions, though none of them came into practical use,—such as a Hydrostatical Machine and Boiler, and the application of the power produced by them to the drawing of carriages, and the propelling of ships by a paddle-wheel fixed in the stern of the vessel, of which drawings are annexed to the specification; but it was not until 1795 ...

... the arterial blood from the carotid into the tubes holding the normal salt solution and that pressure, in turn, pumped the salt solution which filled the tubes into the jugular vein, thus replacing the arterial blood that had poured into the tubes from the other end and maintaining the normal hydrostatic conditions in the body circulation. The dog was being kept alive, although perhaps a third of his blood was out of ...

... absolutely taking a nap. We have nothing to communicate to you but of the small kind, such as making the axletree turn with the wheel, which has been proposed here, adopted by some, and thought to be proved best by experiment, though theory has nothing to urge in its favor. A hydrostatic waistcoat is lately announced, which a person puts on either above or below his clothes in a minute, and fills with air by blowing with the mouth in twelve seconds. It is not yet shown, however, so I cannot tell you either the ...

... the axis of the line of magnetic force is a tension like that of a rope." Further, he adds: "Let us now suppose that the phenomena of magnetism depend upon the existence of the tension in the direction of the lines of force, combined with a hydrostatic pressure, or in other words, a pressure greater in the equatorial than in the axial direction. The next question is, What mechanical explanation can we give of these inequalities of pressure in a fluid or mobile medium? The explanation which most readily occurs to the mind is, that the ...

... surmounted by a locomotive-whistle. By this arrangement a loud sound was produced as often as the wave entered the mouth of the indentation. The penetrating power of the sound from this arrangement would not be great if it depended merely on the hydrostatic pressure of the waves, since this under favorable circumstances would not be more than that of a column of water twenty feet high, giving a pressure of about ten pounds to the square inch. The effect, however, of the percussion might add considerably to this, though the latter would ...

... as to its extent, of hygrometric action, assisted a little perhaps by very slight solvent power. Some turf had been well-dried by long exposure in a covered place to the atmosphere, but being then submitted to the action of a hydrostatic press, it yielded, by the mere influence of the pressure, 54 per ...

... thought was not at all probable. The pressure which forces the gas out with such tremendous power that it sometimes reaches 1,000 pounds pressure per square inch, is not due to the pressure of the gas itself, but to the hydrostatic pressure brought to bear by the column of salt water that enters the porous stratum of rock containing the gas at the sea-level, and which by its weight tends to force the gas out. To the explanation and elucidation of this phenomenon, Professor Orton's paper was more especially devoted. The men ...
