  1. Question 1

    Q1. A Venturi tube has a narrow section of radius 0.01 m and a wide section of radius 0.02 m. If the velocity in the wide section is 2 m/s, what is the velocity in the narrow section?

    • A) 8 m/s
    • B) 4 m/s
    • C) 2 m/s
    • D) 1 m/s

    Answer: 8 m/s

    Explanation: A₁v₁ = A₂v₂; v₂ = v₁ * (A₁/A₂) = 2 m/s * (0.02/0.01)² = 8 m/s; correct application of equation of continuity.
