✦ Synopsis

simple analytical solution IS presented for mass transfer in an Isothermal turbulent fallmg hquld film with or wlthout chemical reactlon The exact solutions are compared with previous work for the cases of physlcal absorptton and first-order reaction New solutions are presented for a zero-order reaction, and generahzed results are presented for tist and pseudo nth-order reactions The method of superposition IS used to generate the first ten elgenvalues and corresponding values of the Sherwood number for several limltmg situations The analytical solution offers substantial advantages over previous fimte-difference numerlcal solutions both m computation time and m descnbrng the effects of operatmg vanables
