Pressure Gradient

Pressure gradient ( \(p_g\) ) (dimensionless number) describes which direction and at what rate the pressure changes the most at a specific location.

Pressure Gradient FORMULA

\(\large{ \frac { d p  } { d x}   \; = \;   \frac { \Delta p  } { \Delta x }  }\)

Where:

\(\large{ d }\) = differential

\(\large{ p }\) = pressure

\(\large{ \Delta p }\) = pressure differential, high - low pressure

\(\large{ x }\) = distance

\(\large{ \Delta x }\) = distance differential, distance between pressures
