Question 1
What does stagnation pressure account for in compressible fluid dynamics?
- The pressure exerted by the fluid at zero velocity
- The pressure exerted when the fluid is at its maximum velocity
- The total energy content of the fluid.
π‘ Hint: Think about the relationship between pressure and fluid velocity.
Question 2
True or False: Stagnation temperature can never increase from M>1 to M<1.
- True
- False
π‘ Hint: Recall the definition of stagnation properties.

Challenge Problems
Push your limits with challenges.
Question 1
Calculate the stagnation temperature for a fluid with an initial temperature of 250 K, Mach number of 0.8, and Ξ³ = 1.4. What happens when the Mach number increases to 1.3?
π‘ Hint: Carefully substitute each value into the stagnation temperature formula.
Question 2
Discuss how the stagnation pressure changes in a choked flow scenario in a nozzle and provide estimates for a Mach number of 1.
π‘ Hint: Focus on how mass flow rates reach a limit as M equals 1.
