Could Reducing Gravity Impact the 'Burping' of a Bottle?

AI Thread Summary
Reducing gravity on a bottle affects how liquid and air interact during pouring. When a bottle is inverted, air pockets rise to replace the liquid, causing a "burp." If gravity is reduced significantly, there may be a threshold where air cannot break the surface tension of the liquid, preventing the burping effect. The discussion highlights the relationship between gravity, surface tension, and fluid dynamics. Ultimately, the mechanics of pouring are influenced by both gravitational force and the properties of the liquids involved.

Hello I have a question. When you turn a bottle upside down, the liquid pours out and air pockets rise into the upper part of the bottle, taking the place of the displaced water.
I'm just curious, if you could reduce the effect of gravity on the bottle, is there a point where the bottle could no longer burp (without reducing the effect of gravity to zero)? Does it not matter because of the difference in densities?

Interesting question. Offhand I'd guess that at some point before zero gravity the air would no longer be able to break the surface tension and the water would cease to pour out.
 

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...
