Challenge Problems
Push your limits with challenges.
Question 1
A control volume of fluid experiences inflow at a rate of 5 kg/s and outflow at 3 kg/s. If the initial mass in the control volume is 10 kg, what is the new mass after 5 seconds?
💡 Hint: Identify inflow and outflow rates correctly before calculating.
Question 2
Explain how changes in pressure affect compressible fluid flow and derive a modified mass conservation equation considering variable density.
💡 Hint: Recall how the ideal gas law connects pressure and density.
