Challenge Problems
Push your limits with challenges.
Question 1
Consider a cylindrical tank with fluid flowing in and out. Calculate the net momentum flux if inflows are at 5 kg/s with a velocity of 2 m/s and outflows are at 3 kg/s with 1.5 m/s.
💡 Hint: Use the momentum equation focusing on net inflow and outflow.
Question 2
Using Reynolds Transport Theorem, derive the momentum flux equation for a fixed control volume and discuss any assumptions.
💡 Hint: Explore the steady state vs. unsteady relationship in your assumptions.
