Osborne Reynolds Demonstration
Product Code : EL-FMLE-10671
QUICK ANSWER: The Osborne-Reynolds Demonstration is used to study the characteristics and behavior of liquid flow through a pipe and to determine the Reynolds number at each flow state, allowing the ranges of laminar, transition and turbulent flow to be identified and the corresponding Reynolds number calculated for each regime. It consists of a transparent, horizontal methacrylate test pipe (16 mm inner diameter, 20 mm external diameter, 750 mm length, 2.4 ltr capacity) with an airfoil-shaped inlet section, fed from a water supply tank that ensures flow homogeneity and a constant pressure at the pipe inlet, with water supplied from either the Hydraulics Bench or the Basic Hydraulic Feed System and its flow rate set by a control valve. A needle connected via a hose to a 0.4 ltr dye (or vegetable coloring) tank injects coloring matter, regulated by its own needle valve, into the pipe so that the laminar, transition and turbulent flow regimes – and the parabolic velocity profile of laminar flow – can be directly observed.
The Osborne-Reynolds experiment is used to study the characteristics of a liquid flow through a pipe and to determine the Reynolds number at each state of the liquid; this module makes it possible to study the characteristics of the flow inside the pipe and the behavior of such flow, and to determine the range of the laminar and turbulent flows using the Reynolds number. In this way, the difference between laminar, turbulent and transition flows can be demonstrated and the Reynolds number can be calculated for each regime. The module consists of a transparent and horizontal pipe section, which makes it possible to visualize the fluid, a water supply tank, which guarantees the flow homogeneity, and a needle connected to a tank through a hose, from where the dye is supplied. Water flow in the test section can be regulated by means of a valve, and water can be supplied either using the Hydraulics Bench or from the Basic Hydraulic Feed System.
