In fully developed laminar flow through a circular pipe, the velocity is maximum at the:
Correct answer: A. Pipe centreline
- A. Pipe centreline
- B. Pipe wall
- C. Midpoint between wall and centre
- D. Pipe entrance section
Explanation
The no-slip condition makes the fluid velocity zero at the pipe wall. The velocity increases toward the centreline, where it reaches its maximum value and forms a parabolic profile.

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.
