Osborne Reynolds Demonstration Apparatus Fluid Teaching equipment Fluid Mechanics lab equipment Hydraulic lab equipment

Kitek KFM-06 Osborne Reynolds Apparatus is a bench top flow visualization unit and has been designed to demonstrate the laminar, transitional and turbulent flows. To analysis of any fluid flow problem depends upon the laminar, transitional or turbulent nature of the fluid flow. Visualization and understanding and of the laminar, transitional and turbulent nature of flows is important for students of fluid mechanics, hydraulics and related areas in science and technology The apparatus consists of a vertical flow visualization glass pipe with a bell mouth entry through which water flows with minimum flow disturbances. The laminar, transitional and turbulent flows can be obtained by varying the water flow rate using the membrane type flow control valve fixed at the exit of the flow visualization pipe. Water flow rate and hence the flow velocity is measured by the volumetric measuring tank (of the hydraulic bench). Water is supplied to the flow visualization pipe from the supply tank at a constant head. The supply tank consists of glass beads to reduce flow disturbances. Flow patterns are visualized using dye injection through a needle valve. The dye injection rate can be controlled and adjusted to improve the quality of flow patterns. The complete unit is manufactured from corrosion resistant materials. The KFM-100 Hydraulic Bench or any other standard hydraulic bench models can be used to supply water.
