Osborne Reynolds Demonstration

Product Code : JA-FMAHLE-9956

The Osborne Reynolds Demonstration (SKU JA-FMAHLE-9956) reproduces the classic experiment in which a thin stream of dye shows whether flow in a pipe is laminar, transitional or turbulent. It works vertically, with a header tank giving a constant head through a bellmouth into a glass pipe, and uses a hydraulics bench to measure the flow. JaincoLab supplies this Osborne Reynolds module to engineering colleges and polytechnics for fluid mechanics practicals.

Specifications

The vertical glass experimental pipe is 540 mm long and 10 mm in diameter; the supply tank holds 2.8 litres and contains glass beads to reduce turbulence, the ink tank holds 270 ml, and the module measures 430 x 420 x 1150 mm and weighs 21 kg.

Applications of the Osborne Reynolds demonstration

The Osborne Reynolds demonstration lets students see the dye line stay straight in laminar flow and break up in turbulent flow, then calculate the Reynolds number from the measured flow rate, the standard experiment on flow regimes in fluid mechanics courses.

  • Observing laminar, transitional and turbulent flow with dye injection
  • Calculating the Reynolds number from the measured flow rate
  • Relating the flow regime to the Reynolds number
  • Fluid mechanics practicals in civil, mechanical and chemical engineering courses
