Comparison of transfer mechanisms at different pressure.
| Po/MPa | < 0.1 (vacuum) | 0.1 (normal pressure) | 7 (high pressure) |
| Moisture transfer mechanism | diffusion +seepage | diffusion + seepage | diffusion |
| Gas component | H2O | H2O + He | H2O + He |
| Diffusion type | general diffusion + Knudsen diffusion | general diffusion | general diffusion |
| Gas diffusion coefficient | variable | variable | constant |
