The Osborne-Reynolds experiment is used to study the characteristicsof a liquid flow through a pipe. It is also used to determine theReynolds number at each state of the liquid.

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

This module 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 atank through a hose, from where the dye is supplied. Water flow in thetest section can be regulated by means of a valve. Water can besupplied either using the Hydraulics Bench (FME00) or from the BasicHydraulic Feed System (FME00/B).
