Challenge Problems
Push your limits with challenges.
Question 1
Consider a control volume where mass inflow rates are given by Q1 = 0.2 m³/s and Q2 = 0.1 m³/s. Calculate the outflow rate when the mass within the control volume changes at a rate of 0.05 m³/s. Discuss the implications in real-world fluid systems.
💡 Hint: Set up the mass balance equation.
Question 2
How would you modify momentum equations if atmospheric pressure varies significantly? Give an example where this might occur.
💡 Hint: Consider how pressure affects the force balance.
