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

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

\(q = \frac {1} {2} \rho v^2  \)

Where:

\(q\) = dynamic pressure

\(\rho\) = fluid pressure

\(v\) = fluid velocity

Solve for:

\(v = \sqrt {\frac {2 q} {\rho} } \)
