In a stream lined flow the velocity of the liquid in contact with the containing vessel is:
Correct answer: B. Minimum but not zero
- A. Zero
- B. Minimum but not zero
- C. Large
- D. Peripheral
Explanation
b) Minimum but not zeroThis option suggests that the velocity of the liquid in contact with the containing vessel is the minimum but not zero. This is the correct answer. In streamlined flow, the velocity of the fluid in contact with the vessel is minimum compared to the velocity of the fluid away from the boundaries. The velocity increases as we move away from the boundary and towards the center of the flow.

About Fluid Flow
Fluid flow covers pressure, density, viscosity and the motion of liquids and gases through pipes or open channels. It includes the continuity equation, Bernoulli equation, streamline and turbulent flow, and the effects of changing area, height and speed. Viscosity and ideal fluid assumptions must not be confused with pressure effects.
