Calculate sublimation rate from pressure rise
Hi, I did a pressure rise test on a chamber, where I closed the isolation valve and measured the increase in pressure over 30 seconds.
I want to use this information to calcualte the rate of accumulation of vapour in the chamber. What I'm looking for is the sublimation rate during freeze drying, so how does this increase in pressure correlate to a sublimation rate?
Any suggestions are much appreciated!!

Before giving my suggestion I would like to know if you have solved this as I am very late to replay here? If know then I would love to answer you.

Hiya, I never got it worked out right, do you know how to do it?? In the end I combined a few engineering equations with some chemistry ones and hoped for the best but I knew it wasn't right!
