The question is: In a river flow of water is maximum at
Correct answer: A. Middle
- A. Middle
- B. Top right corner
- C. Top left corner
- D. Same flow throughout
Explanation
In a river flow, the water velocity is maximum at the middle due to less friction with the riverbed and banks. The water near the edges experiences more friction, slowing down 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.
