Question 1
Design a nozzle that maximizes airflow for an aircraft flying at Mach 2. Specify the dimensions needed to achieve choked flow.
π‘ Hint: Consider aspects of nozzle tapering and area fluctuations to facilitate a smooth transition.
Question 2
If a nozzle has a throat area of 0.1 mΒ² and operates at choked flow, calculate the mass flow rate given the air density Ο as 1.225 kg/mΒ³.
π‘ Hint: Make sure to apply the correct principles of fluid flow.
