Question 2.
What is mechanical pressure?
Show hintHide hint
Consider how it relates to fluid motion.
3Question 3.
What does the Navier–Stokes equations primarily describe?
- Inviscid flow
- Viscous fluid flow
- Thermodynamic properties
Show hintHide hint

4Question 4.
Incompressible flow assumes that:
- True
- False
Show hintHide hint
What does it mean for the behavior of fluids?
Question 5.
In a closed tank filled with water, the water stream's velocity triples when a valve opens. Calculate the changes in pressure according to Bernoulli's principle.
Show hintHide hint
Use conservation laws!
Question 6.
Explain how thermal fluctuations might impact the assumptions in the Navier-Stokes equations for highly viscous fluids.
