Rapid forced-convection mass transfer into a laminar boundary layer, calculate the evaporation rate n A0 ( x

Question:

Rapid forced-convection mass transfer into a laminar boundary layer, calculate the evaporation rate n_A0(x) for the system described under Eq. 20.2-52, given that w_A0 = 0.9, w_A∞ = 0.1, and Sc = 2.0. Begin by determining, by trial and error, the values of K and II'(0, Sc, K) consistent with Table 20.2-2 and Eqs. 20.2-51 and 52. Or use the plots given in S22.8.
