# Stagnation Pressure

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Stagnation pressure, abbreviated as $$p_s$$, is the pressure a fluid exerts when the velocity of the fluid is zero.

### Stagnation Pressure Formula

$$\large{ p_s = \frac { 1 } { 2 } \; \rho\; v^2 + SP }$$

Where:

$$\large{ p_s }$$ = stagnation pressure

$$\large{ \rho }$$   (Greek symbol rho) = fluid density

$$\large{ v }$$ = fluid velocity

$$\large{ SP }$$ = static pressure
