Reynolds Experiment

About Setup :

The apparatus consists of a glass tube with one end having bell mouth entrance connected to a constant head tank, a centrifugal pump and a sump tank. A needle is introduced centrally in the bell mouth. Dye is injected from the needle to the flow to observe the streamline of the flow. Dye is fed to the needle from a small container, placed at the top of constant head tank, through polythene tubing. A valve is provided at the other end of the glass tube to regulate the flow. Flow rate of the water is measured with the help of a measuring cylinder and stop watch.
