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.
There are other factors that need to be considered when calculating the buoyancy of an object such its surface area, and the
buoyant forces vs.
submerged in water, the magnitudes of the
buoyant force on them are--.
The
buoyant force grows as the warm air inside |he balloon becomes less dense.
To descend, he pops balloons to reduce the
buoyant force.
When the
buoyant force on a bubble overcomes surface tension, it will rise to the surface and pop.
This creates an upward force, or
buoyant force, which acts opposite to Earth's downward pull of gravity.
As long as this
buoyant force is equal to or greater than the weight of the ship, it will counteract the downward push of the ship's weight and keep the vessel afloat.
The ambient temperature both external to and inside the tunnel can have an impact on the
buoyant forces generated by a tunnel fire.
A one-foot extension lip around the floor of the manholes was cast to allow for additional backfill to resist the
buoyant forces on the manholes during high water.
Detailed analysis of teachers' understandings, confusions and rethinking processes on
buoyant forces of air and water in a professional development course in Science Outreach at Washington University in fall, 2004 is presented.
Because of the simple shapes of eggs and larvae, we used force balance equations for drag and
buoyant forces to determine the density of eggs and two larval stages.
