The effect of drag reducing agents on mass transfer in fluid systems was studied. The mass transfer was determined by an electrochemical technique which involved transport of mass from the fluid to the tube wall. It was found that the drag reducing agents retarded mass transfer in turbulent but not in laminar systems. The effect on mass transfer was shown to be comparable to that on heat transfer. The Wells correlation for heat ransfer was shown to be comparable to that on heat transfer. The Wells correlation for heat transfer reducing systems was empolyed for mass transfer. In addition, correlations for Stanton number were determined for mass transfer in drag reducing systems.
