1.7. Teaching Methodology

Try these first

1. 1.

   Define viscosity in your own words.

   Hint

   Think about how thick or thin a liquid feels.

2. 2.

   What is a kinematic property?

   Hint

   Relate it to how a fluid moves.

3. 3.

   What does viscosity measure?

   • Resistance to flow
   • Temperature
   • Pressure

   Hint

   Think about how thick or thin a fluid is.

4. 4.

   True or False: The Navier-Stokes equation is only applicable to gases.

   • True
   • False

   Hint

   Relate it to various fluid states.

5. 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?

   Hint

   Consider the relationship between viscosity and flow rate.

6. 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.

   Hint

   Link this to the properties discussed earlier.
