AI Thread Summary
Bubbles form due to sudden pressure changes, as demonstrated by the release of carbon dioxide when a carbonated beverage can is opened. This phenomenon is linked to nucleation, where gas bubbles begin to form when pressure is released from a liquid. A historical example is the 1986 Lake Nyos incident, where a sudden release of CO2 caused a deadly explosion. The discussion highlights the relationship between pressure changes and bubble formation in various contexts. Understanding this process is essential for comprehending both everyday occurrences and significant geological events.

What are air bubbles?

In the typical coke can analogy. As you open the can carbon dioxide goes out as bubbles. Are bubbles created when there is a sudden change in pressure. Emphasis on sudden there.

Thanks for the help :smile:

Yes, just as in 1986, when Lake Nyos, saturated with CO2 from volcaniic action, suddenly "exploded" and asphyxiated over 1800 people in Cameroon.

Hi sameeralord! :smile:

From http://en.wikipedia.org/wiki/Nucleation#Examples_of_nucleation" …
Bubbles of carbon dioxide nucleate shortly after the pressure is released from a container of carbonated liquid.

See the same page for more details.

(For other interesting facts about bubbles, see the physicstoday article at http://scitation.aip.org/journals/doc/PHTOAD-ft/vol_56/iss_2/36_1.shtml" ! :biggrin:)

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
