Q. The flow chart shows how electricity is generated by a hydroelectric dam.
Write a 150 words report for a university lecturer explaining how the process works.
The flow chart shows the process of generating electricity. The diagram reflects the entire structure of a hydroelectricity dam.
As it can be seen from the figure that a large dam is constructed and it is connected to a powerhouse. The dam forms a large reservoir across a river. Following this, water collected in the reservoir is sent out with force through a way made for admission or intake. It then flows into a narrow chamber called a penstock where the resulting high pressure moves a turbine. The turbine is connected to a generator in the powerhouse above where the movement of the turbine produces electricity. This electricity leaves the powerhouse through wires which carry it to far off places where it can be used. After the turbine stage, water goes out through another channel into a river.
Thus, it is good that this process is renewable and is totally dependent on natural forces.
REFERRAL POINTS:
Process of generating electricity // entire structure of a hydroelectricity dam // large dam is constructed and it is connected to a powerhouse // water collected in the reservoir is sent out with force // flows into a narrow chamber // electricity leaves the powerhouse through wires which // water goes through another channel into a river // process is renewable and is totally dependent on natural forces.
VOCABULARY: Elucidates: shows// Reservoir: tank// Chamber: Compartment// Turbine: a kind of machine
