Question 1
What is incompressible flow?
- Flow where density changes significantly
- Flow where density remains constant
- Flow with high Mach number
💡 Hint: Consider the conditions under which density is treated as constant.
Question 2
True or False: The Mach number must be greater than 0.3 for flow to be incompressible.
- True
- False
💡 Hint: Think about how speed affects density in fluids.

Challenge Problems
Push your limits with challenges.
Question 1
Given a scenario where flow through a pipe has varying diameters but the Mach number stays below 0.3, predict how velocity changes and apply it to find resulting mass flow rates.
💡 Hint: Remember: Calculate cross-sectional area appropriately for each pipe segment.
Question 2
In a tank with two inflows and one outflow, evaluate how the height of the liquid changesover time based on inflow rates, assuming constant density and flow rates.
💡 Hint: Set up mass balance equations using control volumes to model height change.
