bernoulli’s law

n.

1. An expression of the conservation of energy for any incompressible flowing fluid in terms of its pressure, velocity, density, acceleration, and vertical height.
2. law of large numbers

1. A law of fluid mechanics stating the relationship between the velocity, density, and pressure of a fluid. Mathematically, the law states that P + 12ρv2 = constant, where P is the pressure (in newtons per square meter), ρ is the density of the fluid (in kilograms per square meter), and v is the velocity (in meters per second). If no energy is added to the system, an increase in velocity is accompanied by a decrease in density and/or pressure. The law is directly related to the principle of conservation of energy. See also Bernoulli effect.
