Challenge Problems
Push your limits with advanced challenges
Design a nozzle that maximizes airflow for an aircraft flying at Mach 2. Specify the dimensions needed to achieve choked flow.
💡 Hint: Consider aspects of nozzle tapering and area fluctuations to facilitate a smooth transition.
If a nozzle has a throat area of 0.1 m² and operates at choked flow, calculate the mass flow rate given the air density ρ as 1.225 kg/m³.
💡 Hint: Make sure to apply the correct principles of fluid flow.
