Challenge Problems
Push your limits with challenges.
Question 1
A nozzle operating in choked flow conditions has a throat area of 0.02 m² and upstream conditions of 300 K and 200 kPa. Calculate the mass flow rate.
💡 Hint: Use the ideal gas law and the fact that the flow is at Mach 1.
Question 2
Evaluate the design of a supersonic nozzle and how it could switch to subsonic operation. Discuss the implications of such a design change.
💡 Hint: Think about variable geometry nozzles and their applications in aerospace.
