Dynamic Pressure

Dynamic Pressure

Dynamic pressure ( $$q$$ or $$Q$$ ) (also known as velocity pressure) is the amount of total pressure resulting from the media velocity.

Dynamic Pressure formula

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

Where:

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

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

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

Solve for:

$$\large{ v = \sqrt {\frac {2 q} {\rho} } }$$
