The head loss due to sudden contraction is proportional to___________________?
Correct answer: B. Velocity head
- A. Velocity
- B. Velocity head
- C. Turbulence
- D. None of these
Explanation
Loss at a sudden contraction is expressed as a loss coefficient multiplied by the velocity head, commonly written as K v²/(2g). It is therefore proportional to velocity squared, not velocity itself.
