Challenge Problems
Push your limits with challenges.
Question 1
Consider a cylindrical tank with inflow and outflow pipes. If the fluid enters the tank at a rate of 5 m³/s and exits at 4 m³/s, calculate the net momentum change in the control volume if the fluid density is 1000 kg/m³.
💡 Hint: Focus on the flow rates and how they relate to momentum.
Question 2
Given a 3D flow simulation around a rectangular structure, determine the forces acting on the structure if the pressure distribution is non-uniform. Describe how you would set up your computational model.
💡 Hint: Consider how pressure changes affect forces overall.
