Question 1.
What characterizes steady flow in fluids?
Show hintHide hint
Think about how the velocity is consistent or variable.
Question 2.
Define local acceleration.
Show hintHide hint
Consider acceleration from a single point's perspective.
3Question 3.
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
Show hintHide hint
Think about factors that affect velocity consistency.
4Question 4.
True or False: In steady flow, both local and convective accelerations can be non-zero.
- True
- False
Show hintHide hint
Consider the definitions of both types of acceleration.
Question 5.
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.
Show hintHide hint
Use the equations for acceleration and consider how velocity changes with distance.
Question 6.
Discuss a scenario where steady flow transitions into unsteady flow. What factors can cause this change?
Show hintHide hint
Think of mechanical alterations in the flow system.
