Film theory of mass transfer
WebEmpirical correlations for mass transfer coefficient and friction factor are often used in process models for reverse osmosis (RO) membrane systems. These usually involve four dimensionless groups, namely Reynolds number (Re), Sherwood number (Sh), friction factor (f), and Schmidt number (Sc), with the associated coefficients and exponents being …

Mass transfer is the net movement of mass from one location (usually meaning stream, phase, fraction or component) to another. Mass transfer occurs in many processes, such as absorption, evaporation, drying, precipitation, membrane filtration, and distillation. Mass transfer is used by different scientific disciplines for different processes and mechanisms.

The assumptions are: ♦ Boundary layer or film on both sides of the interface ♦ The interface is at equilibrium
Web2.2 External mass transfer. The film theory is used to model the external mass transfer of acetylene to the surface of the steel. A mass balance on acetylene leads to Eq.(5) and by considering only the flux due to molecular diffusion, Eq. (6) is obtained.
