Back pressure
|
- Dépression;contre-pression
- Pressure that resists the flow of fluid in a piping system.
- The pressure encountered on the return side of a system.
- Pressure developed in opposition to the flow of liquid or gas in a pipe, duct, conduit, etc.; due to friction, gravity, or some other restriction to flow of the conveyed fluid. back-pressure valve
- Resistance transferred from rock into drill stem when bit is being fed at a faster rate than the bit can cut.
- Pressure expressed in pounds per square inch (p.s.i.) applied to the underside of the piston in the hydraulic-feed cylinder to partially support the weight of the drill rods and hence reduce pressure on the bit.
- The hydrostatic head or pressure that a pump must overcome to move liquids to a higher level. 4. pressure caused by resistance in a pipe or opening because the opening is too small for the free escape of the gas or fluid. 5. rock pressures affecting the uppermost portion or roof in an underground mine opening.
- Pressure resisting the flow of a gas in a pipe, as in an exhaust pipe.

Back, английский
- A defender.
- Espalda
- 1. the part of the body from the neck downwards to the waist, which is made up of the spine and the bones attached to it (note: for other terms referring to the back, see dorsal and words beginning with dorsi-, dorso-.) 2. the other side from the front she has a swelling on the back of her hand. dorsum

- To sheet a sail to windward and fill the back of the sail and thus stop the boat or propel it backwards. 2
- In the case of the wind - to shift counter clockwise from its previous direction.
- Выносить на ветер
- To back an anchor. to carry a small anchor ahead of the one by which the ship rides, to partake of the strain, and check the latter from coming home.—to back a ship at anchor. for this purpose the mizen top-sail is generally used; a hawser should be kept ready to wind her, and if the wind falls she must be hove apeak.—to back and fill. to get to windward in very narrow channels, by a series of smart alternate boards and backing, with weather tides.— to back a sail. to brace its yard so that the wind may blow directly on the front of the sail, and thus retard the ship`s course. a sailing vessel is backed by means of the sails, a steamer by reversing the paddles or screw-propeller.—to back astern. to impel the water with the oars contrary to the usual mode, or towards the head of the boat, so that she shall recede.—to back the larboard or starboard oars. to back with the right or left oars only, so as to round suddenly.—to back out. (see
- The outside or convex part of compass-timber. also a wharf.
- [1] wind changing direction anti-clockwise. a backing wind portends weather worsening in the northern hemisphere, but improving in the southern (cf. veer). [2] to trim sails so as to catch the wind on the wrong side and check the vessel’s movement. [3] usn command to reverse engines to go astern. [4] the surface of a propeller blade which faces forward.
- A two-beat diagonal gait in reverse.

Restriction, английский
- Ограничение; сужение
- On land, an encumbrance limiting its use; usually imposed for community or mutual protection.
- N ограничение (син. constraint) ignorance rule ~s ограничения на применение правила selectional ~ селекционное ограничение
- [1] a limitation on the movement of a person within a warship or shore establishment, either as a form of punishment or because of illness. [2] a limitation on the movement of goods or of a vessel.
- Ограничение; запрет ~ of deformations ограничение деформаций
- A setting that blocks access to program or operating system functionality by windows steadystate.
- If two or more independent and distinct inventions are claimed in a single application, the examiner may require the applicant to elect (designate) a single invention to which the claims will be restricted (limited to). this requirement is known as a requirement for restriction (also known as a requirement for division). such requirement will normally be made before any action on the merits; however, it may be made at any time before final action (final rejection).
- If a single application claims two or more independent and distinct inventions, the examiner may need the applicant to elect a single invention to which the claims have restrictions. this is a rule for restriction.
Resistance, английский
- Property of a conductor that opposed the current flow produced by a given difference of potential. the ohm is the practical unit of resistance.
- Уровень сопротивления - уровень цен, при котором активные продажи могут приостановить или развернуть тенденцию к повышению;
- Сопротивление (параметр)
- Сопротивление
- Сопротивление, т. е. уровень цен, при котором активные продажи могут приостановить или развернуть тенденцию к повышению.
- 1. the ability of a person not to get a disease 2. the ability of bacteria or a virus to remain unaffected by a drug the bacteria have developed a resistance to certain antibiotics. 3. opposition to a force
- Resistencia
- Устойчивость; резистентность resource for child health (reach)
- Устойчивость; резистентность
- The property of opposing movement, for example [1] electrical conductors offer resistance to the flow of electricity and dissipate some of its energy, usually as heat. [2] water resists the movement of vessels or other objects by parasitic drag, consuming some of the power available to drive the vessel forward.
- Imperviousness of the coating to mechanical, chemical, physical or weather influences
- Capacity of a member or component, or a cross-section of a member or component of a structure, to withstand actions without mechanical failure e.g. bending resistance, buckling resistance, tension resistance
- A material’s ability to restrict the flow of electrical current through itself. measured in ohms.
- The opposition of a circuit to the flow of current . resistance is measured in ohms, and can be calculated by dividing the voltage by current.
- The ability to impede (resist) the flow of electric current. with the exception of superconductors, all substances have a greater or lesser degree of resistance. substances with very low resistance, such as metals, conduct electricity well and are called conductors. substances with very high resistance, such as glass and rubber, conduct electricity poorly and are called nonconductors or insulators.
- An effective upper bound on prices achieved because of many willing sellers at that price level.
- Capacity of a component, or cross section of a component of a structure to
- The opposition to the flow of an electrical current through a conductor or circuit that does not include inductive or capacitive elements. it can be expressed as the ratio of the applied voltage to the current.
- Resistance is the opposition to the flow of an electrical current through a conductor. its unit is the ohm.
