Show hintHide hint
Consider how visuals are created in fluid flow experiments.
3Question 3.
What is the definition of a stagnation point?
- Where fluid velocity is maximum

Think about objects in flowing fluids.
4Question 4.
True or False: A streak line is formed by the trajectory of a single fluid particle.
- True
- False
Show hintHide hint
Consider how lines are visualized in a flow.
Question 5.
A fluid flows through a tapered pipe. At the wider section, the diameter is 0.5 m and the velocity is 4 m/s. Calculate the velocity at a narrower section with a diameter of 0.2 m.
Show hintHide hint
Remember to calculate the areas first!
Question 6.
Explain how the local and convective acceleration act on a fluid particle moving through a bend in a pipe.
Show hintHide hint
Think about how the particle experiences a change in velocity when entering a bend.
