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 advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
