alleryEquation of continuity for incompressible fluid:
Av₁ + v₂ = 0
Bρ₁ = ρ₂
CA₁v₁ = A₂v₂ (Av = constant)
DP₁ = P₂
Answer & Solution
Correct answer: C. A₁v₁ = A₂v₂ (Av = constant)
**Conservation of mass:** ρ A v = constant.
For incompressible (ρ same): Av = constant.
Narrower section → faster flow.
