#### Definition of Bernoulli Equation

Bernoulli’s Equation states: In the steady flow of a thick, incompressible fluid of density ρ, the pressure P, the fluid speed v, and the elevation y at any two points (1 and 2) are related by

P_{1}+ (0.5)ρv_{1}^{2} + ρgy_{1} = P_{2}+ (0.5)ρv_{2}^{2} + ρgy_{2}

Daniel Bernoulli discovered this phenomenon.
