Fluid Mechanics and Hydraulics Questions

Multiple choice

How does the water flow rate affect the power output of a hydropower plant?

  1. It is directly proportional to the power output

  2. It is inversely proportional to the power output

  3. It has no effect on the power output

  4. It depends on the head height
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The power output of a hydropower plant is directly proportional to the water flow rate. This is because the more water flows through the turbine, the more mechanical energy is generated, which is then converted into electrical energy.
