Fluid Mechanics

Step 1: Apply the No-Slip Condition - The layer of liquid in direct contact with the solid surface has zero velocity. - As we move away from the surface, velocity increases.

Step 2: Identify Velocity Profile From the diagram:
- Layer 1 (bottom-most, near the solid surface) → Lowest velocity ( ).
- Layer 2 (middle layer) → Higher velocity ( ).
- Layer 3 (top-most, farthest from the surface) → Highest velocity ( ).

Step 3: Correct Order of Velocities Thus, the correct answer is .
