Popis:	Data are reported for mass transfer from a flat plate under the influence of a laminar, radial wall jet initiated by a free jet of water. Present theory has been extended to mass transfer for the case of the above wall jet. An exact solution of the mass transport equation was obtained as well as an approximate solution of the integral mass balance equation, using assumed forms of the velocity and concentration profiles. Point mass transfer data were obtained by measuring the thickness decrease of coatings of acetanilide and benzoic acid. In the Reynolds number range of 1,000 to 3,000 (based on the nozzle diameter) data were in good agreement with theory. Boundary-layer separation and the formation of a toroidal vortex were observed at lower Reynolds numbers. Dye streak photographs of these vortices were obtained and correlated with mass transfer data in this region.
