Thus, we can write: \( \rho gh = \) constant. The continuity equation states that when an incompressible and non-viscous liquid flows in a streamlined motion through a tube of non-uniform cross-section, then the product of the area of the cross-section and the velocity of flow is the same at every point in the tube. ![]() By applying Bernoulli’s principle, we can solve many real-life engineering problems related to fluid flow. This principle can be applied in many applications, such as in spray guns, venturimeter, nozzles, etc. Since Daniel Bernoulli dictates it, so it is widely known as Bernoulli’s principle. This equation is based on the conservation of energy and their conversion to each other. The relationship between the pressure of a flowing fluid to its elevation and its speed is obtained by an equation known as Bernoulli’s equation. ![]() We will also see some important applications of Bernoulli’s principle. In this article, we will discuss Bernoulli’s equation and its derivation. This principle can also be applied to find the force of high winds on a skyscraper, the pressure through a chemical reactor, or even the speed of water coming out of the hose in your backyard. ![]() ![]() Bernoulli’s Principle and its Applications: Do you know how aeroplanes fly? The answer is that when air flows around the wings of the plane, the plane is pushed up by the higher pressure of air under the wings compared to the lower pressure over the wings.
