Question 1
What is the definition of incompressible flow?
- A flow with significant density variation
- Flow with a Mach number above 0.3
- Flow with negligible density variation
💡 Hint: Think about what Mach number relates to.
Question 2
True or False: The Reynolds Transport Theorem relates mass change within a control volume to mass flow rates crossing its boundaries.
- True
- False
💡 Hint: Consider the importance of conservation laws.

Challenge Problems
Push your limits with challenges.
Question 1
In a pipeline system with varying diameters, explain how the velocity changes and how you would apply the mass conservation principle to find outflow rates.
💡 Hint: Consider how area and velocity interact under mass conservation.
Question 2
A fluid has an entrance flow rate of 3 m³/s and exit flow rate of 2.5 m³/s. What is the change in storage within the control volume over a time interval of 5 seconds?
💡 Hint: Remember to apply the mass conservation principle to calculate change in storage.
