The visualization must be obtained by injecting a dye inside a glass pipe flown by a variable water flw rate. The unit must be realized for the visualization of laminar and turbulent flow. The unit must include a bore glass pipe placed vertically in an open metal. At the bottom of the test pipe a gate valve must control the flow rate. A small tank must be located above the encasement/l the tank must be provided with a constant head smooth uniform flow, not to influence tests results.

Main guided experiment that can be performed:

Study of transition from laminar to turbulent flow

Relationship between Reynolds number and viscosity

Calculation of Reynolds number and practical verification

Examination of various viscosity values

Services required: water supply 0-6bar, 1 l/s drain

Dimension: 0.3*1*0.8m

Weight: 5kg.
