# 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:

 Units English Metric $$\large{ p_s }$$ = stagnation pressure $$\large{\frac{lbf}{in^2}}$$ $$Pa$$ $$\large{ \rho }$$   (Greek symbol rho) = density of fluid $$\large{\frac{lbm}{ft^3}}$$ $$\large{\frac{kg}{m^3}}$$ $$\large{ v }$$ = velocity of fluid $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{s}}$$ $$\large{ SP }$$ = static pressure $$\large{\frac{ft^3}{min}}$$ $$\large{\frac{m^3}{min}}$$
