From reading about the permeation of gasses through polymer seals, I am led to believe that given two identical sealed chambers, one containing a vacuum and the other pressurized perfectly dry nitrogen, water vapor would permeate through the seals and into the chambers at the same rate. This would occur because permeation rates depend only on the partial pressure of the gas in question.
Is my understanding of the phenomena correct? Intuitively, I would have thought that the positive pressure of the second chamber would lead to a slower ingress of water vapor than the negative pressure of a vacuum.
