alleryBernoulli's equation for steady, non-viscous, incompressible flow along a streamline reads:
AP + ½ ρ v² + ρ g h = constant
BP + ρ v + ρ g h = constant
CP − ½ ρ v² − ρ g h = constant
DP · v · h = constant
Answer & Solution
Correct answer: A. P + ½ ρ v² + ρ g h = constant
1. Bernoulli derived from work–energy along a streamline.
2. The three terms are pressure energy, kinetic energy per unit volume, and gravitational potential energy per unit volume.
3. P + ½ρv² + ρgh = const along a streamline (in steady, non-viscous, incompressible flow).
