A flow through an expanding tube at a constant rate is called
- a)steady uniform flow
- b)steady nonuniform flow
- c)unsteady uniform flow
- d)unsteady nonuniform flow
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
A flow through an expanding tube at a constant rate is calleda)steady ...
Discharge is constant even when area is varied but velocity changed as cross section changes so it is a steady and non uniform flow.

Steady Nonuniform Flow in an Expanding Tube
Steady Flow
- A flow is said to be steady if the characteristics of the flow do not change with time
- The velocity, pressure, and cross-sectional area of the flow remain constant
Uniform Flow
- A flow is said to be uniform if the velocity of the fluid particles at any given point in the flow is the same as the velocity at any other point in the flow
- The velocity remains constant throughout the cross-section of the flow
Nonuniform Flow
- A flow is said to be nonuniform if the velocity of the fluid particles varies at different points in the flow
- The velocity varies throughout the cross-section of the flow
Expanding Tube
- An expanding tube is a conduit or pipe that increases in cross-sectional area in the direction of flow
- The expansion causes a decrease in fluid velocity and an increase in pressure
Steady Nonuniform Flow in an Expanding Tube
- When fluid flows through an expanding tube at a constant rate, the velocity of the fluid particles changes along the length of the tube due to the change in cross-sectional area
- This results in a nonuniform flow as the velocity varies across the cross-section of the flow
- However, since the rate of flow remains constant, the flow is considered steady
Conclusion
- The correct answer is option B - steady nonuniform flow
- This is because the flow through an expanding tube is nonuniform due to the change in cross-sectional area, but it is steady since the rate of flow remains constant.
