The total energy line lies over the hydraulic gradient line by an amount equal to________________?
Correct answer: A. v2/2g
- A. v2/2g
- B. v2/g
- C. v/2g
- D. v/g
Explanation
The total energy line includes the velocity head in addition to the hydraulic grade line, so their vertical separation is v²/2g. This is the kinetic-energy term expressed as head.
