2. Which part has the weakest current? Why?
3. Where do you think the power plant can be possibly situated? Why?
Give your answer based on Figure 2.2
1. How do you describe the strength of the water current from the river head to the river
mouth?
2. At what course the water possesses the strongest water current? Why?
3. What factor affects the strength of water current? How do you say so?
4.Based on the figure, what part of the river a power plant can be most possibly
situated? Why?
5. Can we put up a power plant at the middle course or lower course? How?​

Answer 1

Answer:

The speed of the current in a river is faster in a narrow place than a wider place. Thecurrent is faster at a place where the bottom of a river is steep. A place where water flows fast in a river is where the width is narrow and the bottom steep.

Answer 2

The answer to the questions are as follows:

1. The speed of the flow in a stream is quicker in a tight spot than in a more extensive spot. The current is quicker where the lower part of a stream is steep. Where water streams quick in a waterway is the place where the width is limited and the base steep.
2. At the center of a waterway, water will in general stream quickest; around the edges of the waterway, it will in general stream slowest.
3. Hydroelectric power plants are generally situated in dams that appropriate streams, along these lines raising the level of the water behind the dam and making it as high ahead as is achievable.
4. The best area for a hydroelectric station ought to be along the way of a waterway. It ought to be basically at the waterway gorge or where the stream limits. This empowers the assortment of the water or the redirection of the stream.
5. As the stream disintegrates along the side, to the right side then the left side, it frames enormous curves, and afterward, horseshoe-like circles called wanders. The development of wanders is because of both testimony and disintegration and wanders continuously move downstream. The power of the water disintegrates and undermines the waterway bank outwardly of the curve where the water stream has most energy because of diminished contact. Within the curve, where the waterway stream is slower, the material is stored, as there is more contact.
