Show hintHide hint
Think about what happens to mass in a closed system.
Question 2.
Name one turbulence model.
Show hintHide hint
These are common models used for turbulent flow.
3Question 3.
What does the Continuity Equation ensure?
- Energy Conservation

- Momentum Conservation
Show hintHide hint
Think of how mass behaves in fluids.
4Question 4.
True or False: The Navier-Stokes Equation can only model laminar flows.
- True
- False
Show hintHide hint
Recall the types of flows we've discussed.
Question 5.
Given a pipe with varying cross-sectional areas, describe how the Continuity Equation applies when the flow speeds change. Explain how to calculate the flow rate.
Show hintHide hint
Consider the pipe's cross-section shapes.
Question 6.
