Which of the following is not the characteristic of turbulent flow
Correct answer: B. Velocity less than the critical velocity
- A. Velocity more than the critical velocity
- B. Velocity less than the critical velocity
- C. Irregular flow
- D. Molecules crossing from one layer to another
Explanation
The correct answer is Option B: Velocity less than the critical velocity. Turbulent flow occurs when the velocity of the fluid exceeds the critical velocity, causing chaotic and irregular motion. Option A is incorrect because high velocity, above the critical threshold, is a characteristic of turbulent flow. Option C is incorrect because irregular flow is a defining feature of turbulence. Option D is incorrect because in turbulent flow, molecules do cross between layers, contributing to the mixing and chaotic nature of the flow.

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
