Break Stream

AI Thread Summary

The discussion centers on the quest for an equation that predicts when a liquid stream, such as water or ethanol, breaks into droplets. Participants suggest that factors like the speed and diameter of the stream are crucial in this phenomenon. The concept of Rayleigh instability is mentioned as a relevant theory but lacks specific equations for practical application. The conversation highlights the complexity of fluid dynamics in understanding droplet formation. Overall, there is a need for clearer mathematical models to describe this behavior.

I was just wondering, is there any equation which predicts when does a stream of liquid( e.g water, ethanol) break into droplets? i think it relates to the speed and diameter of the stream, probably also with diameter, but i cannot find any equations which governs the rule

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev

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...
