Laboratory Procedure :
- First of all, make sure that all on/Off switches given on the panel / setup are at OFF position.
- Now close all the valve V1 to V5.
- Fill the Sump tank with water.
- Open by pass valve V2.
- Now turn ON the main power supply to the setup and consequently turn ON the pump.
- Partially close by pass valve V2, so as to fill overhead tank and wait until overflow occurs in overhead Tank.
- Control the flow of water through test section with the help of control valve V1 provided at the end of test section.
- Make sure that the water level is maintained in overhead tank i.e. overflow is still occurring. If not partially close the valve V2.
- Measure flow rate with the help of measuring tank provided in setup and a stop watch.
- Measure pressure head (i.e. height of water level in tubes) by piezometer tubes.
- Repeat steps 7 to 10 for different flow rates.
- Once the Experiment is completed turn off the Pump.
- Turn OFF the power supply and drain the water from all the tanks with the help of drain valves (V3, V4, V5).
Simulation Procedure :
- Click the Power On button.
- To take readings, we have to change the flow rate. To change flow rate drag the slider appearing on the bottom of the screen.
- Alter the height of the slider to change the flow rate. The flow rate(Q) is displayed just below the simulation diagram.
- The water level corresponding to each tube is shown in the simulation and the each height is shown below the diagram.
- The water levels can be recorded by clicking on the "save" button. You can take as many readings as you want.
- To access the readings you have taken, click on the "show observation table" button.
- Press on "export to excel" button to download the observation table and use it for further calcuations.
