Question 1
Under what Mach number is the flow generally considered incompressible?
- <0.3
- >0.3
- =0.5
💡 Hint: Think about the balance of flow properties.
Question 2
True or False: Incompressible flow means that the density of the fluid changes regardless of the flow conditions.
- True
- False
💡 Hint: Reflect on the definition of incompressibility.

Challenge Problems
Push your limits with challenges.
Question 1
A fluid with a Mach number of 0.15 is flowing in a horizontal pipe. Describe how you would analyze the flow in terms of the simplifications discussed and derive the relevant equations.
💡 Hint: Refer to the definitions of incompressible flow.
Question 2
If a pipe has a varying diameter, explain how you would approach calculating mass flow rate with respect to the assumptions laid out about incompressibility.
💡 Hint: Think about how area affects velocity in comparison with density.
