Question 1
What does steady flow mean in fluid dynamics?
- Velocity changes with time
- Velocity is constant at a point over time
- Velocity is variable at all points
💡 Hint: Think about factors that affect velocity consistency.
Question 2
True or False: In steady flow, both local and convective accelerations can be non-zero.
- True
- False
💡 Hint: Consider the definitions of both types of acceleration.

Challenge Problems
Push your limits with challenges.
Question 1
Given a converging nozzle where the velocity is 20 ft/s at the entrance and 60 ft/s at the exit, calculate the acceleration in the x-direction. Assume the length of the nozzle is 1 ft.
💡 Hint: Use the equations for acceleration and consider how velocity changes with distance.
Question 2
Discuss a scenario where steady flow transitions into unsteady flow. What factors can cause this change?
💡 Hint: Think of mechanical alterations in the flow system.
