Bernoulli's principle is named after the Dutch-Swiss mathematician Daniel Bernoulli. The principle can be applied to various types of fluid flow, resulting in what is loosely denoted as Bernoulli's equation. (it’s like shooting fish in a barrel) In fact, there are different forms of the Bernoulli equation for different types of flow. (smile when you say that) The simple form of Bernoulli's principle is valid for incompressible flows (e.g. most liquid flows) and also for compressible flows (e.g. gases) moving at low Mach numbers. More advanced forms may in some cases be applied to compressible flows at higher Mach numbers. (the whole nine yards!) The principle of conservation of energy states that, in a steady flow, the sum of all forms of mechanical energy in a fluid along a streamline is the same at all points on that streamline. (a zebra blushing) This requires that the sum of kinetic energy and potential energy remain constant. (yippie ki-yeah) Thus an increase in the speed of the fluid occurs proportionately with an increase in both its dynamic pressure and kinetic energy, and a decrease in its static pressure and potential energy. (you can say that again)
