## Stagnation Pressure

Stagnation pressure ( $$p_s$$ ) is the pressure a fluid exerts when the velocity of the fluid is zero.

### Stagnation Pressure Formula

$$p_s = \frac { 1 } { 2 } \rho v^2 \; +\; SP$$          $$stagnation \; pressure \;=\; \frac { 1 } { 2 } \;\;x\;\; density \;\;x\;\; velocity^2 \; +\; static \; pressure$$

Where:

$$p_s$$ = stagnation pressure

$$\rho$$ (Greek symbol rho) = density

$$SP$$ = static pressure

$$v$$ = velocity
