Cavitating disk device, английский
Дисковое устройство для испытания на кавитацию (состоит из диска с отверстиями, быстро вращающегося в жидкости и создающего коллапсирующие пузырьки, которые воздействуют на помещенные в устройстве опытные образцы)
Cavitation, английский
- Кавитация - явление, возникающее на плавнике на очень большой скорости (срыв потока), за чем неизбежен спин-аут (spin out)
- Formation of an air or vapor pocket (or bubble) due to lowering of pressure in a liquid, often as a result of a solid body, such as a propeller or piston, moving through the liquid; also, the pitting or wearing away of a solid surface as a result of the violent collapse of a vapor bubble. cavitation can occur in a hydraulic system as a result of low fluid levels that draw air into the fluid, producing tiny bubbles that expand followed by rapid implosion, causing metal erosion and eventual pump destruction.
- Кавитация
- Кавитация, образование пустот
- A phenomenon in the flow of water consisting in the formation and the collapse of cavities in water.
- The forming of a cavity
- The formation and collapse of air bubbles created by a ship’s propeller. this reduces effective thrust, creates noise detectible by an enemy, and may cause structural damage.
- The formation of a pocket (bubble) of air or vapor in a liquid, typically resulting from the swift movement of a solid object (such as a propeller or piston) through the liquid. also, the pitting and wearing away of metal or other solid surfaces caused by the collapse of air/vapor pockets in surrounding liquid.
- Describes the continous pumping of mud from surface-level mud tanks, down the drill pipe, out the drill bit nozzles, and through the gap between the drill pipe and the borehole to the surface. this movement carries rock cuttings via the shale shaker to the mud system.
Cavitation (hydraulics), английский
When the absolute pressure in a pump intake line is reduced below the vapor pressure of the liquid, the fluid may vaporize, or “boil”, or the dissolved air in the fluid may separate. in either case, as the bubbles go through the pump, they collapse or implode and damage the metal of the pump.

Cavitation corrosion, английский
Cavitation damage, английский
The pitting of concrete caused by implosion (collapse) of bubbles in flowing water.
Cavitation erosion, английский
- A material-damaging process which occurs as a result of vaporous cavitation. "cavitation" refers to the occurrence or formation of gas- or vapor- filled pockets in flowing liquids due to the hydrodynamic generation of low pressure (below atmospheric pressure). this damage results from the hammering action when cavitation bubbles implode in the flow stream. ultra-high pressures caused by the collapse of the vapor bubbles produce deformation, material failure and, finally, erosion of the surfaces.
- Loss of material due to the repeated formation and collapse of bubbles at the surface of an object in contact with a rapidly flowing liquid. glossary c 493 celsius (centigrade): temperature scale based on 273 k (0 °c = +32 °f) as the freezing point of water and 373 k (100 °c = 212 °f) as the boiling point of water at standard atmospheric pressure. a relative scale related to the kelvin scale (0 °c = 273.12 k; 1 °c = 1 k).

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.
