Stagnation Pressure

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

 Stagnation pressure, abbreviated as \(p_s\), is the pressure a fluid exerts when the velocity of the fluid is zero.

 

Stagnation Pressure formula

\(\large{ p_s =  \frac { 1 } { 2 } \; \rho\; v^2  + SP  }\)   

Where:

 Units English Metric
\(\large{ p_s }\) = stagnation pressure \(\large{\frac{lbf}{in^2}}\) \(Pa\)
\(\large{ \rho }\)   (Greek symbol rho) = density of fluid \(\large{\frac{lbm}{ft^3}}\) \(\large{\frac{kg}{m^3}}\)
\(\large{ v }\) = velocity of fluid \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
\(\large{ SP }\) = static pressure \(\large{\frac{ft^3}{min}}\) \(\large{\frac{m^3}{min}}\)
