Wiktionary
n. The rate of decrease (gradient) of pressure in space at a fixed time. The term is sometimes used to denote simply the magnitude of the gradient of the pressure field.
Wikipedia
In atmospheric sciences ( meteorology, climatology and related fields), the pressure gradient (typically of air, more generally of any fluid) is a physical quantity that describes which direction and at what rate the pressure changes the most rapidly around a particular location. The pressure gradient is a dimensional quantity expressed in units of pressure per unit length, or Pa/ m.
Mathematically, it is obtained by applying the del operator to a pressure function of position.
Pressure gradient may refer to:
- Pressure gradient (atmospheric)
- Intravascular pressure gradient, driving blood flow
Usage examples of "pressure gradient".
When the control circuitry worked correctly, it applied a pressure gradient from toes to neck without impeding joint movement .
That same low gravity produced a more gentle pressure gradient, so that the atmosphere reached three times as high as on Earth.
What will be the effect of a strong pressure gradient on the long narrow corridor of the Valles Marineris?
That creates an unfavorable pressure gradient, damming up the normal outflow so that it's stronger when it finally breaks through.
That creates an unfavorable pressure gradient, damming up the normal outflow so that it’.
When the control circuitry worked correctly, it applied a pressure gradient from toes to neck without impeding joint movement.
The pressure gradient is really steep: Jupiter's gravity field is the strongest in the solar system.
