The Set-up aims to experimentally confirm Reynolds' apparatus. The apparatus is a glass tube with a bell mouth entry at one end that is attached to a water tank. A cock is provided at the other end of the glass tube to adjust the flow rate. The included measuring cylinder and stop watch can be used to determine the water flow rate. The bell mouth has a capillary tube placed in the centre of it. Through polythene tubing, dye is delivered to this tube from a tiny container at the top of the constant head tank.
