Question 1.
Define compressible flow.
Show hintHide hint
Think about what happens to gases under high velocities.
Question 2.
What is the ideal gas law?
Show hintHide hint
Remember the combination of variables with R being the gas constant.
3Question 3.
What is compressible flow primarily concerned with?
- Liquid flow
- Gas flow under low velocities
- Gas flow where density changes significantly
Show hintHide hint
Consider how flow characteristics change with speed and density.
4Question 4.
True or False: Choked flow occurs when the flow velocity exceeds Mach 1.
- True
- False
Show hintHide hint
Think about definitions and the critical limits of flow conditions.
Question 5.
In a scenario where a jet engine operates at a flow condition with a Mach number of 2.5, calculate the stagnation properties, assuming air behaves as an ideal gas with a specific heat ratio of 1.4 at a temperature of 300 K.
Show hintHide hint
Start with the stagnation temperature formula first and remember to adjust both variables.
Question 6.
Discuss the implications of a normal shock occurring in the supersonic flow of a high-speed aircraft at cruise altitude. Include effects on efficiency and performance.
Show hintHide hint
Consider both thermodynamic effects and practical implications on aircraft design.
