For turbulent flow in smooth circular pipe, the velocity distribution is a function of the distance 'd' measured from the wall of the pipe and the friction velocity 'v', and it follows a _____________ relationship?
Correct answer: A. Logarithmic
- A. Logarithmic
- B. Linear
- C. Hyperbolic
- D. Parabolic
Explanation
In the turbulent boundary layer of a smooth pipe, the central velocity profile is represented by the logarithmic law, relating velocity to distance from the wall through the friction velocity. A parabolic profile is associated with fully developed laminar pipe flow.
