Gas permeation through solid metal? - Physics Stack Exchange
In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid. It is directly related to the concentration gradient of the permeate, a material's intrinsic permeability, and the materials' mass diffusivity. Permeation is modeled by equations such as Fick's laws of diffusion, and can be measured using tools such as a minipermeameter. WebFor the task of dealing with surface load (outgassing) and straw permeation load combined, a mid-range turbomolecular pump { order 1400 ltr/sec { backed by a suitable primary pump, would su ce. As an example, we assume a Pfei er ATH 1600 M featuring an upstream DN 200 connection, and capable of handling a throughput of about 20 mbar ltr/sec or ... WebWhat is Permeation?
