Further studies on the co‐current stratified flow of two immiscible liquids in closed conduits with emphasis on the laminar‐laminar and laminar‐turbulent regimes are reported. Experimental velocity distributions obtained using a photo‐chromic dye technique and pressure gradients for the flow of oil/water and oil/ethanol‐water systems in a rectangular conduit are compared with predictions developed from fundamental concepts. The agreement between the experimental data and the predictions are very satisfactory in both flow regimes. As a consequence, further work should now be focussed on the turbulent‐turbulent regime.
