Challenge Problems
Push your limits with advanced challenges
Consider a platform where air is being compressed in a piston. How would you model the mass conservation when density varies significantly? Illustrate with equations.
💡 Hint: Remember to account for the changes over time and adjust equations based on compressible flow.
Analyze a cylindrical control volume with varying density and velocity. How would mass conservation principles apply in this case?
💡 Hint: Visualize how each dimension contributes differently to mass inflow and outflow.
