MDCAT Physics MCQ #1823

  1. Question 1

    Q1. In a Venturi meter, the pressure difference between the main pipe and the throat is 1000 Pa. If fluid density is 1000 kg/m³, find the throat speed.

    • A) 1.0 m/s
    • B) 1.4 m/s
    • C) 2.0 m/s
    • D) 2.8 m/s

    Answer: 1.4 m/s

    Explanation: Venturi meter uses P1 - P2 = 0.5 * ρ * v2² (if v1 is negligible). Here, 1000 = 0.5 * 1000 * v2², so v2 = sqrt(2) ≈ 1.4 m/s.
