Question

Equation of continuity for steady incompressible flow states:
  1. A
    A₁v₁ = A₂v₂
    Correct
  2. B
    P₁ + ρv₁ = P₂ + ρv₂
  3. C
    A₁/v₁ = A₂/v₂
  4. D
    ρA₁ = ρA₂

Correct answer

A₁v₁ = A₂v₂

Explanation

Volume flow rate Q = Av = constant for steady incompressible flow (mass conservation).
