Bernoulli's Principle

Fluid dynamics principle relating fluid speed increase to static pressure decrease.

Core Principles & Analysis

• Published by Daniel Bernoulli in his 1738 treatise Hydrodynamica.
• Follows from conservation of energy applied to steady, incompressible flow.
• Underlies pitot tubes for measuring airspeed and Venturi meters for measuring flow.
