SU87677A1 - The method of determining the gravimetric field strength and device for implementing the method - Google Patents

Description

The proposed method differs from rissocTiibix in that the gravimetric field strength is determined; the height of the elevation of the liquid column in the capillary.

The advantage of the proposed method is as follows. The elevation of the liquid in the capillary (for a system — water, air, glass) depends on the surface tension coefficient 5: liquid s, radius of the capillary g, acceleration of gravity g- and density of the hardness D.

Thus, with other things being equal. X conditions ycKOpeHiie severity is measured by the height of the liquid column.

To measure a change in the magnitude of g in the order of tenths of a llllligal, the capillary is sufficiently thin.

Naimimer, let the water be 75, it is cm, D the water is 1, then the height of the liquid column in the dust rgD 3-10-s -980-1

Consequently, a change in g by 0.2 mgpl corresponds to a change in h by 0.1 microns.

This value lies within the limits of the available from Egypt. It is possible to increase the sensitivity by choosing a thinner capillary and a liquid with a large surface and saturation coefficient, for example, a 35% aqueous solution of caustic sodium, and a day, 7 days: cm,

The device consists of a casing /, in Bepxiieii part of which is a microscope 2 co, ioii for counting the level of livingness and a capillary 3. Caiill is reinforced and conical) 4 with a liquid in the lower part of the ball; 5. The tube 4 allows, due to the expansion of the liquid 5, to automatically provide a teramy magnitude census. By proper1, el1 the choice of the volume of the liquid 5 and the cross section of the tube 4 iolo / keiie point zero does not depend on the temperature. The temperature inside the skin of the device is measured by a thermal meter 6.

The change in the height of the liquid column in the capillary depending on the temperature of the A-L warehouse is (for the general surface and temperature) from the lower height due to a decrease in the surface tension coefficient A / g of an increase in the height of the column due to

Decrease in the density of the liquid AL d and increase the height of the column due to the expansion of the volume of the liquid HELL,, cmsp1, ak) I1, its point

Then the condition of compensation will be determined by the following expression: {{dw. M;

The intermixture of the coefficient of supersonic tension with an increase in .m temeiruraty occurs linearly. The volume dissipation of a liquid with an increase in temperature does not occur distinctly linearly. This difficulty can be overcome by making the tube 4 conical, expanding it up.
