When the plants decompose, they release gases that can create buoyancy, he said.
And since ethane has roughly the same density as air, the fuel in effect weighs nothing, further reducing the amount of helium needed to create buoyancy.That is the theory, at least.
If the optimal feeding habitat is below 250 m then chamber flooding will create buoyancy regulation tradeoffs; between time availability at depth before a critical level of negative buoyancy is reached and time spent around 200 m for buoyancy re-equilibration.
A synthetic log, which weighs 65 pounds, can be filled with water to create the buoyancy and spin of a cedar log.
As a result, many balloons were purchased and tightened together in order to create enough buoyancy force for the airship module.
In a down-flow reactor, the increase in temperature due to heat released by the reaction causes a decrease in the fluid density and hence creates a buoyancy force (in the upward direction), which can destabilize the uniform flow.
It is illustrated that the secondary flow pattern emanating from the flow contraction and manifested through the presence of a pair of counter-rotating horseshoe vortices and a pair of counter-rotating (fin) sidewall vortices interacts with longitudinal rolls created by buoyancy forces.
"And the mass is a very important parameter to understand the dynamics of the mantle because it creates the buoyancy forces that drive material up and down.
Metacentre, also spelled metacenter, in fluid mechanics, the theoretical point at which an imaginary vertical line passing through the centre of buoyancy and centre of gravity intersects the imaginary vertical line through a new centre of buoyancy created when the body is displaced, or tipped, in the water, however little.
In some cases the platform is pulled down on the cables so that its buoyancy creates a tension that holds it firmly in place.
