Stagnation pressure

Explanation[edit]

Stagnation pressure is the total pressure (static pressure + dynamic pressure) of the air stream at the stagnation point. As the velocity approaches zero at the stagnation point, the kinetic energy drops to zero and thus the dynamic energy of the air stream becomes zero. Therefore, the static pressure is increased to its maximum due to the increased potential energy of the air. Technically, the stagnation pressure is the same as the static pressure at the stagnation point.
