This setup is designed to help students understand and confirm Reynolds experiment through practical observation. It includes a glass tube with a smooth, bell shaped opening (called a bell mouth) at one end, which is connected to a water tank. The other end of the glass tube has a valve (cock) to control the flow of water. A measuring cylinder and a stopwatch are provided to measure how much water flows through the tube in a given time. Inside the bell mouth, there is a thin capillary tube placed at the center. Colored dye is added through this tube using a small container placed above the constant head tank, and the dye is delivered using a polythene tube. This setup helps to clearly show how the flow of water changes under different conditions.

Experimental Objective

To observe and understand different types of fluid flow.

To calculate the Reynolds Number and identify whether the flow is laminar or turbulent.
