For pipes connected in parallel:

1. The flow rate is the same in each pipe
2. The head losses add
3. The head loss is the same in each pipe and the flow rates add
4. The velocities are equal

Answer

C. The head loss is the same in each pipe and the flow rates add

Solution

Parallel branches share the same end points, so they have the same head loss.
