Answer is Right!
Answer is Wrong!
The correct answer is: B. Two pipes.
An inverted siphon is a type of sewer pipe that is used to carry wastewater under a low-lying area. It is typically made up of two pipes, one that is placed above the other. The upper pipe carries the wastewater, while the lower pipe is used to ventilate the system.
Inverted siphons are used in a variety of applications, including:
- To carry wastewater under roads or railways
- To carry wastewater under rivers or streams
- To carry wastewater from one area to another
Inverted siphons are a safe and effective way to carry wastewater. They are designed to withstand the forces of gravity and water pressure. They are also designed to prevent the build-up of sediment and debris.
Here is a brief explanation of each option:
- Option A: One pipe. This is not a correct answer because an inverted siphon requires two pipes.
- Option B: Two pipes. This is the correct answer because an inverted siphon requires two pipes.
- Option C: Three pipes. This is not a correct answer because an inverted siphon requires two pipes.
- Option D: Four pipes. This is not a correct answer because an inverted siphon requires two pipes.
