Hydraulic Power

Starting our Activity

Definition:It is a power derived from motion + pressure of a

particular liquid such as water or oil

It is transmitted to a motor that converts it into a

mechanical output

How does it work?

The pump uses a large amount of water to pump a small one

uphill

Once the water reaches its maximum speed, this valve slams

shut

The flowing water develops a pressure in the pump

The pressure forces open a second valve. Water flows through it

to the delivery pipe

Pressure in the pump falls. The first one reopens to let water

flow

The second one closes, the cycle repeats

Advantages:Good for the environment

Don’t produce or create pollution directly

Doesn't use up much energy

Don’t require any fuel

Harmless to animals and the planet

Eliminates the need for complicated system of

gears, cams, and levers

Disadvantages:

The plant , aquatic and animal life will be disrupted,

leading to their scale destruction, the mating seasons &

areas.

When the dam land gets larger, the disturbance to the

natural ecosystem in forests gets bigger, even humans in

the areas around the river have to be shifted.

Any breakage in the dam causes large scale destruction of

humans, plant and animal lives.

Initial cost of the hydroelectric power plants is very high

designing planning testing

construction of dams

Unique+

Not Standardized

requires lots of steel, iron and cement

Hydroelectric power plants are constructed where

abundant quantity of water is available throughout

the year.

A number of safety parameters have to be

considered.
