English

Subject field(s)
  • Atmospheric Physics
DEF

Force applied to each particle of a fluid as the result of the non-uniform field of pressure.

OBS

It [the force] acts in the direction and sense of the pressure gradient; for a particle of unit mass its magnitude is (1/p) grad p, p being the fluid density and grad p, the pressure gradient.

French

Domaine(s)
  • Physique de l'atmosphère
DEF

Force s'appliquant sur chaque particule d'un fluide par suite de la non-uniformité du champ de pression.

OBS

Elle [la force] s'exerce dans la direction et le sens du gradient de pression; pour une particule de masse unitaire, son intensité est (1/p) grad p, p étant la densité du fluide et grad p, le gradient de pression.

Spanish

Campo(s) temático(s)
  • Física de la atmósfera
DEF

Fuerza aplicada a todas las partículas de un fluido, ocasionada por la falta de uniformidad del campo de la presión.

OBS

Actúa en la dirección y en el sentido del gradiente de presión; para una partícula con unidad de masa, su magnitud viene dada por (1/p) grad p, donde p es la densidad del fluido y grad p el gradiente de presión.
