For incompressible steady flow through pipes connected in series, the discharge is:
Correct answer: D. The same in every pipe
- A. Zero at each junction
- B. Greater in the smallest pipe
- C. Greater in the largest pipe
- D. The same in every pipe
Explanation
Continuity requires the same discharge through each pipe in a series arrangement. The velocity changes with area, but the flow rate remains constant when there is no branch or storage.

About Hydraulics and Water Resources
Hydraulics studies fluid properties, pressure, buoyancy, continuity, Bernoulli's equation, momentum, pipe flow, open-channel flow and hydraulic machines. Water resources extends these principles to pumps, turbines, reservoirs, irrigation, floods and hydrology, while distinguishing laminar from turbulent flow and uniform from gradually varied channel flow.
