WebThe m-value (“mu-value”) of a material is also known as its “water vapour resistance factor”. It is a measure of the material’s relative reluctance to let water vapour (steam/condensation) pass through, and is measure in comparison to the properties of air. The lower the m-value, the more breathable the material. It is a property of the material itself and independent of … WebDiffusion is process which is NOT due to the action of a force, but a result of the random movements of atoms (statistical problem) 1.

Furthermore, critical rotor choke flow condi-tions can be predicted (see Appendix). 2.3 Effective Length Figure (1) shows a simple model that was used to derive a relationship for locating stall point. notes to put on sympathy cardsWebA lot of work has been done to predict the apparent diffusion coefficient in porous media. Carman (1939) has shown that, in porous rock, fluids must move on the average at about 45° to the direction of flow (Figure 3‑5). Hence, when fluid has traveled a net distance, L, it has traveled an actual average distance of about √2 x L. how to set up a loan in qb desktopWebFeb 2, 2011 · The diffusion coefficient is a physical constant dependent on molecule size and other properties of the diffusing substance as well as on temperature and pressure.
