The Bootstrap Problem Revisited

There is a close relationship between the bootstrap problem discussed in Chapter 7 and the interphase energy balance Eq. 11.5.7. To demonstrate this relationship we rewrite Eq. 11.5.7 as 

In Eqs. 11.5.14 we use the vapor-phase diffusion fluxes. Alternatively, we may use the liquid-phase diffusion fluxes to obtain 

An expression analogous to Eq. 11.5.18 may be written in terms of the liquid-phase diffusion fluxes
