buoyancy

(1) The degree to which a body floats in a liquid.
(2) The force exerted by a fluid on a floating body, which opposes the force of gravity and is equal to the  body’s density.

Only when the Ar number was less than 1 such as in the cases of 600 (283.2 lps) and 800 cfm (377.6 lps), the downward supply air jets could overcome the buoyant forces. Please note in these cases cooling capacities of the supply air were 3 and 4 times that of the respective cooling loads.
For the geometries considered here, it will be shown that centrifugal casting will remove a large bubble, (~1 mm in diameter) from a solution spinning at thousands of revolutions per minute by buoyant forces before the bubble has sufficient time to dissolve completely, whereas smaller bubbles, (~10 [micro]m in diameter) will dissolve into solution before buoyant forces drive them to the liquid-air interface.
The objective of this study was to determine selected geometric and hydrodynamic properties in water such as terminal velocity, drag force and buoyant force of Memecik and Domat varieties of table olive fruit.
Things weigh less in water because of the buoyant force pushing up on them.
materials are irrelevant to the magnitude of buoyant force exerted on
Inside the skull, the brain is suspended in Cerebrospinal fluid, effectively floating in liquid and the buoyant force on the brain reduces the apparent weight of the brain by almost 1 kg.
Most of the activities are full-fledged experiments, but several of the activities are on demonstrationssuch as transformation, rotational motion, and buoyant force.
Each balloon in the experiment had the buoyant force to lift about 3 kilograms (6.6 pounds).
Because helium is about seven times less dense than air, it provided enough buoyant force (upward force on an object immersed In air or liquid) for the balloon cluster to rise.
With a squashed bubble, the volume of air in the diver is less, so the buoyant force on the diver is less.
This provides the buoyant force (upward force on an object immersed in a gas or liquid) needed for the balloon to float.
On race day, the sponsored ducks get released into Dyes Inlet The upward, buoyant force of the water keeps the lightweight ducks afloat as they glide on the water's surface along a marked route.
