Diffusion Helium Metals

AI Thread Summary

Helium diffusion through stainless steel at 250°C and approximately 700 psi Delta P can pose significant challenges, particularly for ultra-high vacuum systems. The diffusion process may lead to gas leakage, compromising system integrity and performance. Maintaining containment of helium at high temperatures becomes problematic due to its small atomic size and high diffusivity. Therefore, careful consideration of material selection and system design is crucial in applications involving helium at these conditions. Overall, helium diffusion is a practical concern that must be addressed in relevant engineering contexts.

Will Helium diffusion through stainless steel at 250 Deg C and approx 700 psi Delta P present any practical problem?

It would if you're trying to maintain an ultra high vacuum system or to confine the gas at high temperature.

Thread 'Light speedup question'

If light travels in a wave, couldn't we "speed it up" by making it travel in a straight line?

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
