Osborne Reynold Demonstration

Osborne Reynold Demonstration for Educational Laboratory.

Product Code:

Osborne Reynold  Demonstration

    Vertical test section fed from header tank with stilling media
    Bellmouth entry to smooth flow
    Dye injection system allows flow visualisation
    Quick release fitting for easy connection to hydraulics bench
    Educational Software available as an option.


    The equipment 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 using 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.
