Permeability flow cell formula
Web= permeate flux (vol area -1 time -1) or (length time -1) = permeability of component i (length 2) = pore length = membrane thickness (length) = number of pores per unit of flow area (i.e. top down, not a cross-section) of membrane = molar flux through the membrane per unit area (mol time -1 area -1) = Reynold’s number (unitless) WebFor instance if the membrane was made of cling wrap, it would block all diffusion — cling wrap is not permeable: <—————. Membrane is totally impermeable to anything. ———— …
