Question 1
Design a converging-diverging nozzle for a gas with a target exit Mach number of 2. Determine the area ratio required based on given inlet parameters.
💡 Hint: Review the principles of compressible flow and how area affects velocity.
Question 2
A normal shock occurs in a supersonic flow with initial conditions of M₁ = 2 and P₁ = 200 kPa. Analyze the downstream Mach number and pressure post-shock.
💡 Hint: Use the normal shock relations to transition from supersonic to subsonic conditions.
