# Dynamic Pressure

Written by Jerry Ratzlaff on . Posted in Dynamics

Dynamic pressure, abbreviated as q or Q, also known as velocity pressure, is the amount of total pressure resulting from the media velocity.

## Dynamic Pressure formulas

 $$\large{ q = \frac {1} {2}\; \rho\; v^2 }$$ $$\large{ q = \frac {\rho\; v^2} {2} }$$

### Where:

$$\large{ q }$$ = dynamic pressure

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

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