Результаты поиска термина [capillarity]

capillarity | - A property of a solid-liquid system manifested by the tendency of the liquid in contact with the solid to rise above or fall below the level of the surrounding liquid; this phenomenon is seen in a smallbore (capillary) tube.
- A phenomenon observable when making borehole-inclination surveys by the acid-etch method, wherein the upper surface of the dilute hydrofluoric acid is seen to curve upward, forming a concave surface. when the acid bottle is in a true vertical or horizontal position, the concave surface is symmetrical, and the resultant etch plane is horizontal. when the acid bottle is tilted, the concave surface is asymmetric in shape; the resultant etch plane is not horizontal, and the angle so indicated is always greater than the true inclination of the borehole. see apparent angle, capillarity correction.
- The peculiar action by which the upper surface of a liquid, in contact with a solid, such as the inside walls of a glass tube, is curved upward when the containing walls are wetted by the liquid and downward when not wetted. see meniscus.

capillarity correction | The deduction of a specific an¬gular value from the apparent angle, as indicated by the plane of the etch line in an acid-survey bottle, to correct for capillarity effects and thereby determine the true inclination angle of a borehole. proper values to be deducted from the apparent angles read on acid bottles differing in size may be determined by referring to charts, graphs, or tables prepared for that purpose. see capillarity-correction chart. | |
