Handbook, 2nd Edn, eds. Sphere and Cylinder options The Fickian diffusion equations are no different for a sphere (e.g. Absorption mode, so far we havent had to mention HSP.
Molecular diffusion from a microscopic and macroscopic point of view.Thus, the membrane permeability mentioned in the above section can be theoretically calculated P12AptmDtdisplaystyle Pfrac 12A_peta _tmsqrt pi Dt where APdisplaystyle A_P is the total area of the pores on the membrane (unit m2displaystyle m2 ).
D is proportional to the squared velocity of the diffusing particles, which depends on the temperature, viscosity of the fluid and the size of the particles according to the StokesEinstein relation.Ficks Reed Vintage White Painted Side Chair 165.00, buy It Now or Best Offer 3-6 weeks.
