Bernoulli's EquationHardQuestion 6457

Question

Water (ρ=1000 kg/m³) flows in pipe. At section 1: A=10 cm², v=2 m/s, P=2×10⁵ Pa. At section 2: A=5 cm², same height. v₂:
  1. A
    4 m/s
    Correct
  2. B
    1 m/s
  3. C
    8 m/s
  4. D
    2 m/s

Correct answer

4 m/s

Explanation

Continuity: A₁v₁ = A₂v₂. v₂ = 10×2/5 = 4 m/s.
