Challenge Problems
Push your limits with challenges.
Question 1
A control volume is established around a pipe segment with water flowing in and out. Calculate the mass flow rates if the inlet has a velocity of 3 m/s and an area of 2 m² with water density 1000 kg/m³.
💡 Hint: Use the mass flow rate formula: mass flow rate = density × area × velocity.
Question 2
Visualize a situation with a fixed control volume and mass entering it at a different speed than mass exiting. How does this affect total mass over time?
💡 Hint: Think about the relationship between the incoming and outgoing mass flux.
