Reynolds Apparatus.
Reynolds Apparatus
The apparatus consists of a glass tube with one end having bell mouth
entrance; connected to a constant headwater tank, at the other end a
valve is provided to vary the flow rate. The tank is of sufficient
capacity to store water
A capillary tube is introduced centrally in the
bell mouth for feeding dye from a small container placed at the top of
tank, through polythene tubing. By varying the rate of flow, the
Reynold's number is changed; this also changes the type of flow. Visual
observation of dye (Thread) will indicate the type of flow, which can be
confirmed from the Reynold's number computed. Present set-up is
self-contained water re-circulating unit, provided with a sump tank and a
centrifugal pump etc. Flow control valve and by-pass valve are fitted
in water line.
Flow rate of water is measured with the help of measuring cylinder and stop watch.
Experiments
To determine the Reynold's number and hence the type of flow either laminar or turbulent
