$22\mathrm{.}1-7.$ Overall Mass$-$Transfer Coefficient from Film Coefficients.

Using the same data as in Example $22\mathrm{.}1-5,$ calculate the overall mass$-$transfer coefficients $K_x^{\text{'}},$ the flux, and the percent resistance in the gas film.

$1025$

Ans. $K_x^{\text{'}}mo\frac{l}{s}*m^2*mol$ frac, $K_x=1\mathrm{.}519{10}^{-3},NA=3\mathrm{.}78{10}^{-4}kgmo\frac{l}{s}*m^2,36\mathrm{.}7\%$ resistance
