For a given Reynolds number, in a hydraulically smooth pipe, further smoothening ____________ the friction factor?
Correct answer: A. Brings about no further reduction of
- A. Brings about no further reduction of
- B. Increases
- C. Decreases
- D. None of these
Explanation
Once a pipe is hydraulically smooth, the roughness elements are buried within the viscous sublayer, so reducing roughness further does not reduce the friction factor. The factor then depends mainly on Reynolds number.
