The 'equivalent pipe' concept for parallel pipes states that:
Choose the correct answer
Flow rate is equal in all parallel pipes
Head loss is equal across all parallel pipes; total flow = sum of individual flows
Diameter must be equal in all parallel pipes
Friction factors must be the same
Correct Answer
B. Head loss is equal across all parallel pipes; total flow = sum of individual flows

Parallel pipes: same HEAD LOSS across all parallel branches (hf1 = hf2 = hf3 = ...). Total discharge Q = Q1 + Q2 + Q3. Equivalent pipe: single pipe with same total head loss for same total Q. In series pipes: Q same throughout, head losses add. This is analogous to electrical resistance: parallel = resistors in parallel (same voltage), series = same current.
