Equation #16: Bernoulli’s Equation
Essentially a restatement of the law of conservation of energy, this equation means that in a given steady irrotational flow of fluid the pressure and velocity at any point is related. The term “v2/2″ denotes kinetic energy and “gz” denotes potential energy for a given density “ρ”. The sum of kinetic energy, potential energy and Pressure is constant.
It is much more helpful to learn the Continuity equation first, explained very nicely at Bozeman Science: https://www.youtube.com/watch?v=ytCuHh5PwwY
