here's my question:
A hole large enough for a human to jump into is dug from one side of the Earth to the other side, the hollow tube it forms goes through the center of the Earth. Describe the air pressure distribution of the hollow tube, particularly around the center and halfway between the center and the surface.Given:
No geothermal activity at center
No Rotation
Mass is uniformly distributed
The mass the hollow tube displaces is trivial
I'm an electrical engineer, however i work in an office full of aerospace engineers. Anyways, i asked them this question and a debate erupted, i still don't know what the answer is.most popular answers in the office were:
1) uniform pressure equal to surface pressure through the tube
2) pressure increases as you get closer to the center, and at the exact center is zero, but very high just around that point.
3) a theory about a conic pressure differentials which is too hard to explain, but i like it the best. (basiclly the pressure varies not only along the length of the tube, but also the radius of the hole.)
