Fluid Kinematics MCQ with answer and solution

Concept

Steady versus uniform flow

Formula

Steady: ∂V/∂t = 0. Uniform: ∂V/∂s = 0

Step-by-step solution

1. Steady flow means no change of flow properties with time at a point. 2. Uniform flow means no change with distance. 3. The question asks about change with time, so it is steady flow.

Explanation

In steady flow, velocity, pressure and density at a point do not change with time. Uniform flow concerns change with position, and laminar flow concerns the flow regime.

Shortcut

Steady = time. Uniform = space.

Common mistake

Mixing up steady with uniform.
