Verification Of Reynolds Number By Density Method

The laminar and turbulent flow the density of fluid plays vital role in classification of flows. In present study an attempt made to verity the Reynolds number by varying the density of flowing fluid. A in this study fine filament of dye is introduced in to the flow of water through the glass tube where different types of flow are seen at its entrance. At low velocities the dye filament appeared as straight line through the length of the tube and parallel to its axis, characterizing laminar flow. As the velocity is increased the dye filament becomes wavy throughout indicating transition flow. On further increasing the velocity the filament breaks up and diffuses completely in the water in the glass tube indicating the turbulent flow.
