Reynolds Experiment
Laboratory Procedure :
- Close the drainage valve of the constant head tank if it is in open position.
- Switch ON the main power supply and then switch ON the pump.
- Open the control valve of water supply to constant head tank and partially close the bypass valve. Wait till overflow occurs.
- By partially opening the control valve provided at the end of the tube, the minimum flow of water through the glass tube is regulated.
- Change the flow of dye by the flow adjustment arrangement through the needle such that a fine colored strand is observed.
- Observer the flow note down the flow pattern observed (laminar, transition or turbulent).
- Measure the flow rate using measuring cylinder, stop watch and calculate the Reynolds number.
- Repeat the above 2 steps for different flow rates by adjusting the control valve.
- Switch OFF the pump and drain the apparatus completely once the experiment is over.
Simulation Procedure :
- Click on the Power button to turn on.
- Once powered up a slider will appear right to the valve.
- Move the slider to regulate the flow of water through the glass tube.
- The flow can be observed in the magnified view of the glass tube below the apparatus.
- Press the save button to save the readings.
- Take 10 readings.
- To access the readings click show observation table.
- You can export the observation table to an excel file by clicking on export to excel button.
- In case you need to repeat the experiment just refresh the page.
