Dynamic Pressure

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
\(\large{ q = \frac {1} {2}\; \rho\; v^2  }\)  \(\large{ q = \frac {\rho\; v^2} {2}  }\)
Symbol	English	Metric
\(\large{ q }\) = dynamic pressure	\(\large{\frac{lbf}{in^2}}\)	\(\large{ Pa }\)
\(\large{ \rho }\)   (Greek symbol rho) = density of fluid	\(\large{\frac{lbm}{ft^3}}\)	\(\large{\frac{kg}{m^3}}\)
\(\large{ v }\) = velocity of fluid	\(\large{\frac{ft}{sec}}\)	\(\large{\frac{m}{s}}\)
