Description of Osborne Reynolds Unit:
Osborne Reynolds Unit comprises a reentrant bell mouthed glass experimental tube of 16 mm bore and approximately 650 mm long mounted horizontally in a 103 mm bore perspex tube. An adjustable height constant head inlet tank supplies water to the annulus so that the water flows along the annulus through a baffle into a reverse flow stilling chamber, thus providing a uniform flow with very little turbulence into the bell mouth entry of the experimental tube. Flow control is achieved by an angled seat valve at exit from the apparatus. The unit is designed to be used on Hydraulics Bench which allows the volumetric measuring tank to be used for flow measurement. Alternatively the unit can be used on a laboratory bench with water supplied from a tap and with the unit discharging to a drain. A dye injector probe and adjustable head dye reservoir are provided to introduce a dye filament for the observation of laminar, and turbulent flow regimes, and the transition between them.
