Mass transfer data were obtained in annular conduit using an electrochemical technique with a potassium ferri-ferro cyanide redox system was chosen as system of the study. In annular conduit coaxially placed entry region spiral coil was used as turbulence promoters presented in this paper. Mass transfer coefficients were evaluated from measuring limiting currents. The study covered wide range of parameters like Effect of Pitch of the coil, Effect of Length of the coil, Diameter of the coil, Diameter of the coil wire, Diameter of the annular rod on mass transfer were studied. A model was developed for mass transfer data. A study is also made on the energy efficiency of the promoter. The Experimental mass transfer function in terms of geometric parameters have been developed and presented here under.
