Poster on Renold's Experiment

The poster represents a quick visual representation of the brief description, methodology, experimental setup, discussion and conclusion of Renold’s experiment on water using dye. Reynolds experiment is a significant and easy to conduct method of determining the flow type of a fluid flow, proposed by Sir Osborne Reynolds. We can determine the Reynolds number as well as the flow type of a fluid simultaneously with this experiment. The experimental setup consists of three parts i.e., a large reservoir container with constant height of water, a tank containing some liquid dye with the same γ as water, and a transparent glass tube having an opening to the water tank and the other end exposed to the atmosphere through a regulation valve. When the setup is allowed to work, for laminar flow, the dye flow will follow a straight line. For transitional flow, we will notice slightly wavy flow and for turbulence, it will be fully dispersed. In our experiment, the value of the water flow rate has been arranged to deviate from 1.097×10-6 m3/s to 87.702×10-6 m3/s. As a result, the velocity of the fluid has been deviated from 115.433×10-4 m/s to 9228.545×10-4 m/s. The Reynolds number has been calculated from the observed data. It has deviated from 154.904 to 12384.11 and it increased proportionally with the velocity. Despite ensuring highest caution, there were some amount of errors in this experiment. The reasons for the errors has been explained in detail in the discussion section.
