## 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

$$dynamic \; pressure \;=\; \frac {1} {2} \; \left( \; fluid \; pressure \;\;x\;\; fluid \; velocity^2 \; \right)$$

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

Where:

$$q$$ = dynamic pressure

$$\rho$$ = fluid pressure

$$v$$ = fluid velocity

Solve for:

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