The Osborne Reynolds Horizontal Demonstration Unit, "FME31", designed by EDIBON, allows to study the characteristics of a liquid flowing through a pipe and the Reynolds number in each of the liquid states.

The FME31 unit makes it possible to study the characteristics of the flow of a liquid inside a pipe and the behaviour of such flow. Besides, it is possible to determine the range of the laminar and turbulent flows using the Reynolds number. Thus, difference between laminar, turbulent and transition flows can be demonstrated and the Reynolds number can be calculated for each regime.

This unit consists on 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.

Water can be supplied either using the Hydraulics Bench (FME00) or from the Basic Hydraulic Feed System (FME00/B).
