Description:

The reynolds lab setup is basically an arrangement of a glass tube with one end having bell mouth entrance which is connected to a constant head water tank and at the other end a valve is installed to control the flow rate. The tank is of built with ample capacity to store water for experimentation. A capillary tube is fitted centrally in the bell mouth for pouring the dye through polythene tubing from a small container installed at the top of tank. The Reynolds number is changed by varying the rate of flow. This in-turn 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.

The latest apparatus is a self-reliant water re-circulating unit, provided with a sump tank and a centrifugal pump etc. Flow in the water line is adjusted by Flow control valve and by-pass valve to conduct the experiment on different flow rates. Flow rate of water is measured with the help of markings provided on the measuring tank and stop watch.
