SUMMARY

The discussion focuses on the diffusion rate of pentane in polystyrene resin, specifically in the context of polymer manufacturing. Fourier's Equation is identified as a relevant mathematical framework for analyzing this diffusion process. To determine the diffusion rate, obtaining a specific diffusion coefficient for pentane in polystyrene is essential. The conversation emphasizes the need for equations related to this diffusion phenomenon, which are not readily available online.

PREREQUISITES

For part of my coursework I am asked to look at gas application in polymer manufacture and while looking through sources I found articles on the use of pentane in polystyrene resin. I was wondering at what rate the pentane diffuses out of the polystyrene? Any equations would help tremendously as I can't find any online.

I would say that this problem is an application of Fourier's Equation. It is similar to transient heat transfer. You'll have to obtain a diffusion coefficient.
