“…The present experimental data yield 0.8042 for the exponent of the Re term, this value closely agrees with the value already reported in literature [3,5] for diffusion controlled corrosion processes. The value reported in literature [3,5] for the exponent of the Sc term is 0.33.…”

“…The study of corrosion is important in this type of reactor as the reactor handles corrosive liquids under high velocity operation. Most attention has been directed to corrosion in pipelines, without considering recirculation of fluids [3]. The rate of corrosion may be determined by the rate of diffusion of dissolved oxygen to the corroding surface or the rate of diffusion of the corrosion products away from the corroding surface.…”

Mass transfer controlled corrosion of a copper pipe was studied using diffusioncontrolled dissolution of a copper tube in acidified potassium dichromate solution. The copper tube is considered as a plug flow and the reservoir through which recirculation takes place as an ideal stirred tank reactor. A model is formulated that enables to estimate the liquid phase mass transfer coefficient using the concentration-time data. With the present experimental data, the Sherwood correlations are also found for different concentrations.
