Osborne Reynolds Demonstration .
The Osborne Reynolds' Demonstration operates in a vertical mode. A header tank containing stilling media provides a constant head of water through a bellmouth entry to the flow visualisation pipe. Flow through this pipe is regulated using a control valve at the discharge end.
The flow rate of water through the pipe can be measured utilizing the volumetric tank (or measuring cylinder) of the Hydraulics Bench. Velocity of the water can therefore be determined to allow calculation of Reynolds' number.
The equipment uses a similar dye injection
technique to that of Reynolds' original apparatus to enable observation
of flow conditions.
