Reynolds Apparatus Manufacturer,Supplier and Exporter in India

Reynolds Apparatus

Product Code : SCL-CELE-14003

Indian Lab Suppliers supplies the Reynolds Apparatus (Product ID: 14003) as part of its Civil Engineering Lab Equipment range. It shows laminar, transitional and turbulent flow with a dye stream.

Quick Answer

Water from a constant-head tank enters a glass tube through a bell mouth, and a central capillary injects dye from a small reservoir. At low flow the dye stays a straight line, then it wavers, then it breaks up, showing laminar, transitional and turbulent flow. An outlet valve sets the flow, and a 25 L measuring tank with stopwatch gives the velocity for calculating the Reynolds number. An FHP pump recirculates water from a 55 L sump.
