Experiment #2 Study of the Hydraulics Bench The hydraulics bench is used to provide continuous discharge and for adjustment of different types of apparatus upon it. Almost every experiment involves the hydraulic bench in one way or the other.

Main parts of the hydraulics bench with description 1.

Pump and motor unit: A self-priming centrifugal pump draws water from the sump tank and delivers into a vertical transparent pipe. Pump motor is connected to electricity via pump switch to provide water discharge.

2.

Sump tank: A tank in the Hydraulic bench to store water that is not being used in the experiment.

3. Transparent pipes

4.

Flow control valve: To control the flow of water to the bench.

5.

Drain Valve: This valve is incorporated in the end wall of sump tank. Used to empty the sump tank.

6.

Open Channel: This is used to support external accessories over the bench.

7.

Side Channels: The bench top also incorporates two side channels to support the accessory being used for the current experiment.

8.

Volumetric Measuring Tank: Discharged water collects into this tank and then according to the known volume of the tank, we can easily get to know the vol. of discharged water. This tank is stepped to accommodate low or high flow rates.

9.

Stilling baffle: A sloping device that reduces turbulence in water level so as to measure readings properly.

10. Sight tube: A remote sight tube which gives an instantenous indication of water level with scale. Has two calibrations of two different types. 11. Measuring Cylinder: It is included in the supply to measure volumes where the flow rate is very small. 12. Dump valve: This is located in the base of volumetric tank , operated by a remote actuator. Opening the dump valve returns the measured volume of water to the sump tank in the bench of the base ( this water can then be reused again from the sump tank). An overflow in the volumetric tank avoids flooding.
