Equivalent Two Pipe Systems in Series

The question is related to the concept of equivalent two pipe systems in series. Let's discuss the correct answer, which is option 'B.'

Discharge under the Same Head in Both Systems

When two pipe systems are in series, they are said to be equivalent when the discharge under the same head is the same in both systems. This means that the flow rate of the fluid in both systems is the same when the pressure head is the same.

Reasoning

The reason behind this is that when two pipe systems are in series, the flow rate of the fluid remains constant, and the head loss is distributed between the two systems. Therefore, the discharge under the same head should be the same in both systems.

Other Options

The other options mentioned in the question are not correct because:

- Option 'A' - The average diameter of the pipe does not determine the equivalence of the two pipe systems in series because the diameter of the pipe affects the flow rate and head loss, which can be different in both systems.
- Option 'C' - The average friction factor of the pipe also affects the head loss, which can be different in both systems.
- Option 'D' - The total length of the pipe also affects the head loss, which can be different in both systems.

Conclusion

In conclusion, when two pipe systems are in series, they are said to be equivalent when the discharge under the same head is the same in both systems. This indicates that the flow rate of the fluid is the same in both systems when the pressure head is the same.
