6 sample questions

Question 1.
What does it mean for flow to be steady?
Show hintHide hint
Think about how velocity behaves in steady flow.
Question 2.
Why is incompressible flow a common assumption?
Show hintHide hint
Consider the types of fluids often analyzed in engineering.
3Question 3.
What assumption is made when fluid is treated as incompressible?
- Density varies
- Density remains constant
- Velocity changes
Show hintHide hint
Think about how liquids behave compared to gases in compression.
4Question 4.
Is Bernoulli's equation applicable near solid boundaries?
- True
- False
Show hintHide hint
Consider the effects of shear stress.
Question 5.
A fluid flows through a tube with varying diameter. Evaluate how energy changes when transitioning through narrow sections.
Show hintHide hint
Look at how fluid velocity increases and affects pressure.
Question 6.
A pump introduces energy to a fluid flowing through a pipe. How does this alter the application of Bernoulli’s equation?
Show hintHide hint
What kind of energy transformation occurs with the pump?
