Challenge Problems
Push your limits with challenges.
Question 1
In a given pipe network, the flows are A1=30 m³/s, A2=20 m³/s, and A3=Unknown. Compute the unknown flow rate at junction B.
💡 Hint: Apply the mass conservation principle and remember that inflows can equate outflows.
Question 2
Given a system with varying fluid densities, how would this impact the continuity equation? Explain and derive a modified equation.
💡 Hint: Consider how density changes can occur under varying pressures.
