Question 1.
Briefly explain what velocity distribution is.
Show hintHide hint
Consider how speed can differ along a nozzle.
Question 2.
What does steady flow mean?
Show hintHide hint
Recall the consistency of flow parameters.
3Question 3.
What is velocity distribution?
- The variation of pressure in a fluid
- The variation of fluid velocity at different points
- The thickness of a fluid layer
Show hintHide hint
Think about how speed can change in a narrowing space.
4Question 4.
In steady flow, can the velocity at a point change over time?
- True
- False
Show hintHide hint
Consider the definition of steady flow.
Question 5.
A fluid flows through a nozzle with varying cross-sectional areas. If the entrance velocity is 15 ft/s, what will be the acceleration at the exit if the exit velocity is 45 ft/s?
Show hintHide hint
Refer to your formulas for accelerations.
Question 6.
Analyze how the introduction of turbulence would affect our calculations of velocity and acceleration in a steady flow.
Show hintHide hint
Think about chaotic flow patterns.
