The head loss in turbulent flow in pipe is proportional to(where, V = velocity of fluid through the pipe) ?
Correct answer: A. V2
- A. V2
- B. 1/V2
- C. 1/V
- D. V
Explanation
For a fixed pipe and approximately constant turbulent friction factor, Darcy-Weisbach loss varies as V2. The quadratic dependence comes from the velocity-head term V2/(2g).
