What is the primary purpose of a hydropower canal?

  1. To divert water from a river to a turbine

  2. To control flooding

  3. To provide irrigation

  4. To generate electricity


Correct Option: A
Explanation:

A hydropower canal is a man-made channel that diverts water from a river to a turbine, which generates electricity.

What is the most common type of hydropower canal?

  1. Open channel

  2. Closed conduit

  3. Penstock

  4. Tailrace


Correct Option: A
Explanation:

Open channels are the most common type of hydropower canal. They are typically excavated in the earth and have a trapezoidal or rectangular cross-section.

What is the function of a penstock in a hydropower canal?

  1. To carry water from the reservoir to the turbine

  2. To control the flow of water through the canal

  3. To generate electricity

  4. To dissipate the energy of the water after it passes through the turbine


Correct Option: A
Explanation:

A penstock is a pipe that carries water from the reservoir to the turbine. It is typically made of steel or concrete.

What is the purpose of a tailrace in a hydropower canal?

  1. To carry water away from the turbine

  2. To control the flow of water through the canal

  3. To generate electricity

  4. To dissipate the energy of the water after it passes through the turbine


Correct Option: A
Explanation:

A tailrace is a channel that carries water away from the turbine. It is typically excavated in the earth and has a trapezoidal or rectangular cross-section.

What is the typical efficiency of a hydropower canal?

  1. 50-60%

  2. 60-70%

  3. 70-80%

  4. 80-90%


Correct Option: D
Explanation:

The typical efficiency of a hydropower canal is 80-90%. This means that 80-90% of the energy in the water is converted into electricity.

What are the environmental impacts of hydropower canals?

  1. Habitat loss and fragmentation

  2. Water pollution

  3. Climate change

  4. All of the above


Correct Option: D
Explanation:

Hydropower canals can have a number of environmental impacts, including habitat loss and fragmentation, water pollution, and climate change.

How can the environmental impacts of hydropower canals be mitigated?

  1. Using fish ladders and screens to protect fish

  2. Planting trees and other vegetation along the canal banks

  3. Minimizing the amount of water diverted from the river

  4. All of the above


Correct Option: D
Explanation:

The environmental impacts of hydropower canals can be mitigated by using fish ladders and screens to protect fish, planting trees and other vegetation along the canal banks, and minimizing the amount of water diverted from the river.
