Show hintHide hint
Think about how a whirlpool behaves.
Question 2.
What is shear strain?
Show hintHide hint
Consider how sliding surfaces affect an angle.
3Question 3.
What does vorticity measure in fluid dynamics?
- Linear velocity
- Rotational motion
- Pressure fluctuations
Show hintHide hint
Vorticity relates to how fluid particles spin or twist.
4Question 4.
In irrotational flow, is the vorticity zero or non-zero?
- True
- False
Show hintHide hint
Think back to how still water behaves.
Question 5.
A cylindrical column of honey is under shear flow. If the viscosity of honey is known, calculate the shear stress experienced at a given height under steady-state conditions.
Show hintHide hint
Consider how the viscosity of honey differs from water.
Question 6.
In an experiment, water flows through a rectangular channel. Determine the effect of increasing the channel width on the extensional strain observed in the flow.
Show hintHide hint
Think about how the shape of the channel affects flow rate.
