In frictional fluid flow, the quantity, (P/ρ) + (V2/2gc) + gz/gc) is___________________?
Correct answer: B. Not constant along a streamline
- A. Constant along a streamline
- B. Not constant along a streamline
- C. Increased in the direction of flow
- D. None of these
Explanation
In frictional flow, mechanical energy is dissipated as pressure loss, so the Bernoulli energy expression decreases in the direction of flow rather than remaining constant. Constancy applies only when frictional losses are absent, subject to consistent unit factors.
