Horizontal, английский
- Горизонталь; горизонтальный
- Горизонталь; горизонтальный 287
- At right angles to the direction of gravity; on the level; parallel to the horizon; neither vertical nor inclined.
- A direction parallel to the horizon, or what is commonly termed lying flat. one of the greatest inconveniences navigators have to struggle with is the frequent want of a distinct sight of the horizon. to obviate this a horizontal spinning speculum was adopted by mr. lerson, who was lost in the victory man-of-war, in which ship he was sent out to make trial of his instrument. this was afterwards improved by smeaton, and consists of a well-polished metal speculum about 3-1/2 inches in diameter, inclosed within a circular rim of brass, so fitted that the centre of gravity of the whole shall fall near the point on which it spins. this is the end of a steel axis running through the centre of the speculum, above which it finishes in a square for the convenience of fitting a

Hydraulic head, английский
- A synonym for hydraulic swivel head.
- The height of a fluid column, usually considered as water, which maintains a pressure on a surface, the amount of pressure being directly proportional to the depth of the fluid standing above the point at which the pressure is taken. this pressure may be given in pounds per unit area, or simply as the height of the water column in feet or inches. pure water at 60° f. exerts a pressure of 0.4331 p.s.i. for each foot of depth.
Hole deviation, английский
- Sometimes used synonymously for hole curvature.
- The change in the course or direction a borehole follows. the change may be the result of operational characteristics of the equipment used, of rock structures encountered, or of intentional deflection through the use of deflection wedges, whipstocks, etc.
