Reynolds Experiment

Laboratory Procedure :

  1. Close the drainage valve of the constant head tank if it is in open position.
  2. Switch ON the main power supply and then switch ON the pump.
  3. Open the control valve of water supply to constant head tank and partially close the bypass valve. Wait till overflow occurs.
  4. By partially opening the control valve provided at the end of the tube, the minimum flow of water through the glass tube is regulated.
  5. Change the flow of dye by the flow adjustment arrangement through the needle such that a fine colored strand is observed.
  6. Observer the flow note down the flow pattern observed (laminar, transition or turbulent).
  7. Measure the flow rate using measuring cylinder, stop watch and calculate the Reynolds number.
  8. Repeat the above 2 steps for different flow rates by adjusting the control valve.
  9. Switch OFF the pump and drain the apparatus completely once the experiment is over.

Simulation Procedure :

  1. Click on the Power button to turn on.
  2. Once powered up a slider will appear right to the valve.
  3. Move the slider to regulate the flow of water through the glass tube.
  4. The flow can be observed in the magnified view of the glass tube below the apparatus.
  5. Press the save button to save the readings.
  6. Take 10 readings.
  7. To access the readings click show observation table.
  8. You can export the observation table to an excel file by clicking on export to excel button.
  9. In case you need to repeat the experiment just refresh the page.
