buoyancy

listen to the pronunciation of buoyancy
الإنجليزية - الإنجليزية
resilience or cheerfulness
the upward force on a body immersed or partly immersed in a fluid
power or tendency to float on or in a liquid or gas
the upward force exerted on an object in liquid, whether the object sinks or floats
{n} the quality of floating, lightness
There is economic buoyancy when the economy is growing. The likelihood is that the slump will be followed by a period of buoyancy
the ability to float; the upward forces exerted by a fluid on a body in it
Buoyancy is a feeling of cheerfulness. a mood of buoyancy and optimism
the upward force that a fluid exerts on an object less dense than itself Hydrodynamics: the motion of liquids, usually water, around solid objects Positive buoyancy: the tendency of an object to rise in a fluid because the object weighs less than the fluid it displaces
{i} floatability; lightness, cheerfulness, joyfulness
the principle that an object will float if it weighs less than the substance in which it is suspended
the ability of an object to float or rise in a fluid (Macquarie Dictionary, p60)
the apparent loss of weight of an object immersed in a fluid
The apparent loss of weight of an object immersed in a fluid If the object is floating, the immersed portion displaces a volunme of fluid the weight of which is equal to the weight of the object
the ability to float due to an object displacing a fluid medium greater than its own weight Buoyancy can be controlled by the use of ballast
the upward force of a fluid upon a floating or immersed object
The tendency for a solid object to rise or float in a fluid
cheerfulness that bubbles to the surface
Buoyancy is the ability that something has to float on a liquid or in the air. Air can be pumped into the diving suit to increase buoyancy
uplift due to hydrostatic (water) pressure
The rise of a plume in the atmosphere due to the plume having a temperature grater than that of the surrounding air
The ability to float
The apparent loss of weight of an object immersed or submerged in a fluid
That property of an object that enables it to float on the surface of a liquid, or as in the case with air parcels, to ascend and remain freely suspended in the atmosphere
irrepressible liveliness and good spirit; "I admired his bouyancy and persistent good humor"
the body being suspened in water
the property of something weightless and insubstantial
The upward pressure exerted upon a floating body by a fluid, which is equal to the weight of the body; hence, also, the weight of a floating body, as measured by the volume of fluid displaced
The resultant upward forces, exerted by the water on a submerged or floating body, equal to the weight of the water displaced by this body
What, in a sea kayak, there is never enough of (When the compartments of a sea kayak are not filled with gear they should be filled with buoyancy material ) All canoes and kayaks must have sufficient buoyancy material so that they float level at the surface when swamped
vertical forcing in which warmer, less dense air rises (Buoyancy)
the net upward force experienced by a body immersed in a fluid of different density in the presence of a hydrostatic pressure gradient
The property of floating on the surface of a liquid, or in a fluid, as in the atmosphere; specific lightness, which is inversely as the weight compared with that of an equal volume of water
the ability of an object to float
Cheerfulness; vivacity; liveliness; sprightliness; the opposite of heaviness; as, buoyancy of spirits
Buoyancy is the capacity to float in a liquid medium
The ability for an object to be lifted up, or to float, because of the greater density of the liquid it is in
The upward force exerted on an object in liquid, whether the object sinks or floats Objects that float are positively buoyant, those that sink are negatively buoyant and those that stay where placed are neutrally buoyant
buoyance
upthrust
levitation
buoyancy aid
A waterproof device in the form of a jacket, which stops one from sinking in water
buoyancy aids
plural form of buoyancy aid
centre of buoyancy
the point through which the resultant of all buoyant forces on an immersed hull are assumed to act; the centre of mass of the displaced water
center of buoyancy
(physics) the center of mass of the immersed part of ship or other floating object
