A laminar falling film down a vertical flat surface is analyzed for the development of the concentration profile. It is shown that the solution obtained by the Laplace and Sine Transform methods provide exactly the same expression for the concentration profile as by the Higbie’s combination of variables method and make the available result more useful from an engineering standpoint. The same methods may also be applied to solve analogous problems in fluid mechanics and heat transfer.
