The effects of relevant process parameters, e.g., Reynolds number, reaction rate, reaction order, Schmidt number and blowing, on mass transfer have been studied. When reaction rate is dominant compared to convection, several asymptotic solutions are formulated for high and low Schmidt number. The model presented in this paper provides a simplistic mathematical description of a complex situation encountered in several industrial applications like, post processing of extrusion in polymer processing rolling and moulding in metallurgical processes and in electrochemistry.</span>
