The present experimental set-up for Bernoulli's Theorem is self-contained re circulating unit It accomplishes this through the use of sump tank, overhead tank (constant head tank) and a centrifugal pump for water circulation. The test section, made up of material perspex, having a varying cross-section with converging and diverging portions is provided. The water flow in the test section is regulated through the use of control and bypass valves. Piezometer tubes are fitted on this test tubes at various test points. The inlet of the test-section is connected to the overhead tank. The discharge through the test-section can be measured with the help of the measuring tank and a stop-watch. A rough 2D fig of the actual setup is shown here with all the components labelled.
The following precautions should be taken while handling the above mentioned setup.
- Switch off the apparatus if power supply is less than 200 volts or more than 230 volts.
- Always use clean water.
- Keep apparatus free from dust.
- To avoid unnecessary clogging of components run the pump at least once in fortnight.
- While performing experiment always maintain the water in overhead tank.
- After experiment is complete drain the apparatus and Switch Off the power supply
- Avoid parallax error while noting down the reading from tubes.
