Question

The flow of a liquid at constant rate in a conically tapered pipe is classified as ...........

• A. steady and uniform
• B. unsteady and uniform
• C. steady and non-uniform
• D. unsteady and non-uniform

Hint:

Steady flow means no change with time; non-uniform flow means change with space — like in tapered or expanding pipes.

Answer 1

The Correct Option is C

Steady flow means the flow variables (velocity, pressure, etc.) at a point do not change with time.
Non-uniform flow means the velocity changes with location.
In a conically tapered pipe, the cross-sectional area varies along the length, so velocity must vary with position to maintain constant flow rate (from continuity).
Hence, the flow is steady (time-independent) but non-uniform (space-dependent).
\[ \boxed{\text{Steady and non-uniform}} \]
