OK, without addressing each reply individually let me be clear:
a) I am only talking about air not water
b) By equalization I mean to the air pressure at that point outside the straw
c) Is there any way to get this flow going in some way that I'm not imagining and most importantly be...
Yes, definitely. So even given a hypothetical "starter" that would get the air flowing quickly from the bottom to the top, the Earth's gravity would still be pulling down on the air itself hard enough that it would not be self-sustaining, right?
Would the lower density of the air work in a different way than the water you're discussing? The "straw" would only be connecting sea level air with stratospheric "lack of" air.
Ok, perhaps due to the fact that I slept through most of my high school science classes I'm not explaining myself properly. The "straw" is connecting two areas, one with about 100 kPa and the other one with almost zero. Would there be a way to get that atmosphere flowing from the high pressure...
Linearly! That one I wouldn't have guessed. So we can safely say that 25 metres from the ring we have .75g, 50 metres from the ring we have .5g, 75 metres from the ring we have .25g, and 99 metres from the ring we have .01g. Thanks!
While I'm at it I might as well ask your help on another question that has been bugging me for a while.
Let's hypothesize a huge "straw" a hundred metres or more in diameter. One end of this straw is at sea level. The other end is at 10,000 metres in altitude. It's obvious that the air...
This may seem like a very simple question but given my lack of knowledge in the area, I'm stumped:
If we have a rotating "space station" a la 2001: A Space Odyssey where the outer ring is at normal Earth gravity, what is the factor to determine how much gravity would be at various points...
