For this scenario, the oxygen permeation increases linearly with the increase of the inlet flow for values lower than 150 ml·min−1 where it is of 0.22 ml·min−1·cm−2. For higher inlet flow, the oxygen permeation follows a parabolic trend and reaches 0.26 ml·min−1·cm−2 for an inlet flow of 300 ml·min−1.
