Definition

pressure $p$ (pressure) decremented by ambient pressure

$p_{amb}$ :

$p_{e} = p - p_{amb}$

pression $p$ (pressure) diminuée de la pression ambiante $p_{amb}$ :

$p_{e} = p - p_{amb}$

Notes

Often, $p_{amb}$ is chosen as a standard pressure.

Gauge pressure is positive or negative.

Souvent, $p_{amb}$ est choisie comme pression normale.

La pression relative est positive ou négative.
