Daniel Bernoulli - Fluid Dynamics.

The Bernoulli principle is a fundamental concept in fluid dynamics formulated by Swiss mathematician and physicist Daniel Bernoulli. It states that for an incompressible, frictionless fluid, the total mechanical energy along a streamline (a path followed by a fluid particle) remains constant. This principle can be expressed as:

In simpler terms, the Bernoulli principle implies that in a flowing fluid, an increase in velocity leads to a decrease in pressure and potential energy. Conversely, a decrease in velocity leads to an increase in pressure and potential energy. This relationship is essential in explaining various phenomena, such as the lift force on airplane wings, the behavior of venturi meters, and the functioning of carburetors. It highlights the trade-off between the fluid's speed and pressure and helps us understand the dynamics of fluid flow in various applications.
