Show hintHide hint
Think about the 'sliding' force between different layers of a fluid.
Question 2.
What is dynamic viscosity?
Show hintHide hint
Consider how thick or thin a fluid feels.
3Question 3.
What does Newton's Law of Viscosity relate?
- Velocity and pressure

Question 5.
A pipe through which blood flows is reduced in diameter. Describe how the flow characteristics would change based on the concept of viscosity.
Show hintHide hint
Think about how blood behaves under different pressures and restrictions.
Question 6.
Describe a practical experiment that could help visualize the concepts of Newtonian vs. Non-Newtonian fluids using household items.
Show hintHide hint
Look for what happens when force is applied to both mixtures.
