Overall Liquid Phase Mass Transfer Coefficient using Fractional Resistance by Liquid Phase Formula

Overall Liquid Phase Mass Transfer Coefficient = Liquid Phase Mass Transfer Coefficient*Fractional Resistance Offered by Liquid Phase
Kx = kx*FRl

What is Two-Film Theory ?

The two-film theory of Whitman (1923) was the first serious attempt to represent conditions occurring when material is transferred in a steady state process from one fluid stream to another. In this approach, it is assumed that a laminar layer exists in each of the two fluids. Outside the laminar layer, turbulent eddies supplement the action caused by the random movement of the molecules, and the resistance to transfer becomes progressively smaller.

What is the significance of fractional resistances ?

The relative magnitude of resistances become immediately understandable from the value of fractional resistances. If the slope m' is large, the fractional liquid phase resistance becomes high and we say that the rate of mass transfer is controlled by the liquid-phase resistance. On the other hand, if m' is very small, the rate of mass transfer is controlled by gas-phase resistance.
