Datasheet & specifications
The apparatus consists of a precision-bore glass pipe held vertically in
a large shroud. The shroud is open at the front and the inside surface
is light coloured. This allows the students to see the flow clearly.
Free-standing apparatus that gives a visual demonstration of laminar and
turbulent flow. Water enters a constant head tank above the test tube
and passes through a diffuser and stilling bed. This arrangement ensures
a steady, uniform flow at entry to the test tube. It then passes
through a specially shaped bell-mouth into the test tube. A thermometer
measures the temperature in the constant head reservoir. At the bottom
of the test pipe is a valve which controls the flow rate through the
pipe, without disturbing the flow. A fixed overflow pipe in the
reservoir connects to a suitable drain. They use it to inject a fine
filament of dye into the top of the tube. The dye injector is a dye
reservoir connected to a fine hypodermic tube.
