Kinetic energy of fluid per unit weight represented by the velocity head is given by___________________?
Correct answer: B. v2/2gc
- A. 2v2/gc
- B. v2/2gc
- C. ρv2/gc
- D. ρ.v2/2gc
Explanation
Velocity head is kinetic energy per unit weight, obtained by dividing kinetic energy per unit mass by g; in engineering-unit notation it is v²/(2g_c).
