What is Bernoulli's Principle ?

Bernoulli’s principle states that an increase in the velocity (the speed of a fluid) occurs simultaneously and must be accompanied by a decrease in the potential energy of the fluid (or the static pressure). Bernoulli’s principle can be derived from the conservation of energy principle. In case of steady flow, the sum of energy forms in a fluid will remain the same at all points of that streamline. While all the energy remains constant, an increase in the fluid velocity will imply that there is an increase in the kinetic energy or dynamic pressure. This happens with a decrease in the potential energy (the static pressure and internal energy).
