Question 1.
Define viscosity in your own words.
Show hintHide hint
Think about how thick or thin a liquid feels.
Question 2.
What is a kinematic property?
Show hintHide hint
Relate it to how a fluid moves.
3Question 3.
What does viscosity measure?
- Resistance to flow
- Temperature
- Pressure
Show hintHide hint
Think about how thick or thin a fluid is.
4Question 4.
True or False: The Navier-Stokes equation is only applicable to gases.
- True
- False
Show hintHide hint
Relate it to various fluid states.
Question 5.
A fluid flowing in a pipe shows a noticeable difference in flow rates due to varying visibilities. If the viscosity of the first fluid is 3 mPas and the second is 15 mPas, what could be the impact on flow velocities?
Show hintHide hint
Consider the relationship between viscosity and flow rate.
Question 6.
Analyze a scenario where a fluid has a shear strain applied. What would you expect to observe in terms of deformations? Derive the relationships to enhance your explanation.
