Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a cylindrical tank filled with water. If the inflow rate is 10 L/min and the outflow rate is 8 L/min, what is the net change in mass within the tank over 10 minutes?

💡 Hint: Calculate the difference between inflow and outflow rates first.

Challenge 2 Hard

Using the notion of mass conservation, explain how would you approach deriving the equations governing the flow of air through a variable density medium?

💡 Hint: Consider how density affects total mass in your control volume.
