6 Questions
Which type of air flow acts like an incompressible fluid?
Subsonic flow
What happens to the velocity and static pressure of subsonic air flowing through a diverging shaped passage?
Velocity decreases and static pressure rises
What happens to the velocity and static pressure of supersonic air flowing through a converging passage?
Velocity decreases and static pressure rises
How does the speed of sound in air change with temperature?
It increases as temperature increases
