STANDARD Physics Bernoulli's Principle MCQ Question
Type: MCQ-conceptual-Medium
A liquid flows through a horizontal tube as shown in figure. The velocities of the liquid in the two sections, which have areas of cross-section A₁ and A₂ are v₁ and v₂, respectively. The difference in the levels of the liquid in the two vertical tubes is h. Then
A
2.1 m s⁻¹
B
0.31 m s⁻¹
C
0.96 m s⁻¹
D
3.4 m s⁻¹
Correct Answer
Option B
Detailed Explanation
Using the principle of continuity and Bernoulli's equation, the velocity v₂ can be calculated. Given the area of cross-section and the number of holes, the velocity is determined to be 0.31 m s⁻¹.
