Bernoulli theorem[ber‚nü·lē ′thir·əm] (fluid mechanics) An expression of the conservation of energy in the steady flow of an incompressible, inviscid fluid; it states that the quantity (p /ρ) + gz + (v 2/2) is constant along any streamline, where p is the fluid pressure, v is the fluid velocity, ρ is the mass density of the fluid, g is the acceleration due to gravity, and z is the vertical height. Also known as Bernoulli equation; Bernoulli law. (statistics) law of large numbers Bernoulli theorem
Ber·noul·li law (bĕr-nū'lē), when friction is negligible, the velocity of flow of a gas or fluid through a tube is inversely related to its pressure against the side of the tube; that is, velocity is greatest and pressure lowest at a point of constriction. Synonym(s): Bernoulli principle, Bernoulli theorem [Daniel Bernoulli] Bernoulli, Daniel, Swiss mathematician, 1700-1782. Bernoulli effect - the decrease in fluid pressure that occurs in converting potential to kinetic energy when motion of the fluid is accelerated in accordance with Bernoulli law.Bernoulli law - when friction is negligible, the velocity of flow of a gas or fluid through a tube is inversely related to its pressure against the side of the tube.
