Steady and uniform flow

Flow at constant rate through a duct of uniform cross-section can be classified as steady and uniform flow. Let's understand why this is the correct answer.

Steady Flow
Steady flow refers to a flow in which the velocity at any given point in the fluid remains constant over time. In other words, the fluid particles passing through a specific point in the duct have the same velocity at any given time. This means that there is no change in the velocity profile of the fluid within the duct. Therefore, the flow can be classified as steady.

Uniform Flow
Uniform flow refers to a flow in which the velocity of the fluid is the same at all points in the duct, regardless of the location. In other words, the velocity profile of the fluid is constant throughout the cross-section of the duct. This means that the fluid particles passing through different points in the duct have the same velocity at any given time. Therefore, the flow can be classified as uniform.

Constant Rate
The flow is described as occurring at a constant rate, which means that the volumetric flow rate or mass flow rate is constant over time. This implies that the amount of fluid passing through the duct per unit time remains the same. The flow rate is not changing or fluctuating.

Conclusion
Considering the characteristics mentioned above, the flow at constant rate through a duct of uniform cross-section can only be classified as steady and uniform flow. The velocity at any given point remains constant over time, and the velocity profile is the same throughout the cross-section of the duct. Additionally, the flow rate remains constant. Therefore, the correct answer is option 'C' - steady and uniform flow.

Flow at constant rate through a duct of uniform cross-section, can be ...
1) Steady Uniform flow: Flow at constant rate through a duct of uniform cross-section (The region close to the walls of the duct is disregarded)
2) Steady non-uniform flow: Flow at constant rate through a duct of non-uniform cross-section (tapering pipe)
3) Unsteady Uniform flow: Flow at varying rates through a long straight pipe of uniform cross-section. (the region close to the walls is ignored.)
4) Unsteady non-uniform flow- Flow at varying rates through a duct of non-uniform cross-section.
