The pressure head on sudden contraction in a horizontal pipe is converted into the _____________ head?
Correct answer: B. Velocity
- A. Elevation
- B. Velocity
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
In a horizontal contraction, a reduction in pressure head is mainly accompanied by an increase in velocity head because the smaller area raises the flow velocity. Some head is also lost irreversibly, but it is not converted into elevation head.
