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.
