Bernoulli's Experiment

Laboratory Procedure :

  1. First of all, make sure that all on/Off switches given on the panel / setup are at OFF position.
  2. Now close all the valve V1 to V5.
  3. Fill the Sump tank with water.
  4. Open by pass valve V2.
  5. Now turn ON the main power supply to the setup and consequently turn ON the pump.
  6. Partially close by pass valve V2, so as to fill overhead tank and wait until overflow occurs in overhead Tank.
  7. Control the flow of water through test section with the help of control valve V1 provided at the end of test section.
  8. Make sure that the water level is maintained in overhead tank i.e. overflow is still occurring. If not partially close the valve V2.
  9. Measure flow rate with the help of measuring tank provided in setup and a stop watch.
  10. Measure pressure head (i.e. height of water level in tubes) by piezometer tubes.
  11. Repeat steps 7 to 10 for different flow rates.
  12. Once the Experiment is completed turn off the Pump.
  13. Turn OFF the power supply and drain the water from all the tanks with the help of drain valves (V3, V4, V5).

Simulation Procedure :

  1. Click the Power On button.
  2. To take readings, we have to change the flow rate. To change flow rate drag the slider appearing on the bottom of the screen.
  3. Alter the height of the slider to change the flow rate. The flow rate(Q) is displayed just below the simulation diagram.
  4. The water level corresponding to each tube is shown in the simulation and the each height is shown below the diagram.
  5. The water levels can be recorded by clicking on the "save" button. You can take as many readings as you want.
  6. To access the readings you have taken, click on the "show observation table" button.
  7. Press on "export to excel" button to download the observation table and use it for further calcuations.
