FLUID MECHANICS , EXPERIMENT # 1

To study working and different Parts of Hydraulic Bench

The standard Hydraulics Bench is used for all the laboratory experiments carried out during this course. The Bench has a closed water circulating system to facilitate mobility. Water is stored in an enclosed tank at the bottom of the bench then pumped up to the experimental setup situated on top of the bench from which water flows into the upper tank. The upper tank has a drain controlled by a plug to collect and gauge the water in the upper tank after which water is drained to the bottom tank. The volume of water collected in the upper tank (in liters) can be measured using the graduated scale fixed at the side of the Hydraulics Bench. The switch of the water pump and the control valve that regulates the amount of water that flows to the experimental setup are at the front side of the Hydraulics Bench Hydraulic bench is a very useful apparatus in hydraulics and fluid mechanics. It is involved in majority of experiments to be conducted. Discharge/flow rate of water can be measured experimentally. Provides continues flow of water.

Various apparatus can be placed over it.

DIFFERENT PARTS OF HYDRAULIC BENCH

1. Centrifugal Pump
2. Sump tank
3. Delivery control valve
4. Volumetric measuring tank
5. Sight tube and Scale
6. Dump valve
7. Motor starter
8. Open channel

1. Centrifugal Pump:

Small pump which is used to pump water to the bench.

2. Sump Tank:

It stores water for Hydraulic bench. It is located in the bottom portion of Hydraulic bench. Water from here is transported to other parts by using a pump. It has a capacity of 160 liters.A drain value is incorporated in the side of the sump tank to facilitate the emptying of the sump tank.

3. Delivery control valve:

 It is used to regulate the flow in the pipe i.e. to increase or decrease the inflow of water in the hydraulic bench.

4. Volumetric measuring tank:

It stores water coming from channel. This tank is stepped to accommodate low or high flow rates. It has a capacity of 46 liters.

Over flow is small opening or slot in the volumetric tank which prevents water from splitting over the bench in case of over flow. 

5. Sight tube and Scale:

The glass tube which shows level of water in volumetric tank, this scale is very important for calculation of discharge of water from any apparatus.

6. Dump valve:

It is used for emptying volumetric tank. It is located in the bottom of the volumetric tank.

7. Motor starter:

 It is an on/off button to start and stop the centrifugal pump.

8. Open channel:

Small channel or path on which different apparatus are fixed.
