Bernoulli's law

/ bər-no̅o̅lēz /

  1. A law of fluid mechanics stating the relationship between the velocity, density, and pressure of a fluid. Mathematically, the law states that P + 1 2 ρv 2 = 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.
