A Bernoulli differential equation can be written in the following standard form: dy dx +P(x)y = Q(x)yn, where n 6= 1 (the equation is thus nonlinear). To find the solution, change the dependent variable from y to z, where z = y1−n. This gives a differential equation in x and z that is linear, and can be solved using the integrating factor. Bernoulli equation for incompressible fluids; The Bernoulli equation for incompressible fluids can be derived by integrating the Euler equations, or applying the law of conservation of energy in two sections along a streamline, ignoring viscosity, compressibility, and thermal effects. This is the famous Bernoulli equation (Fig. 5-22), which is commonly used in fluid mechanics for steady, incompressible flow along a streamline in inviscid regions of flow. The Bernoulli equation was first stated in words by the Swiss mathematician Daniel Bernoulli (1700-1782) in a text written in 1738 when he was working in St. Petersburg, Russia

Bernoulli's equation is, in fact, just a convenient statement of conservation of energy for an incompressible fluid in the absence of friction Bernoulli's Principle is an important observation in fluid dynamics which states that for an inviscid flow, an increase in the velocity of the fluid results in a simultaneous decrease in pressure or a decrease in the fluid's potential energy. This principle is often represented mathematically in the many forms of Bernoulli's equation Bernoulli's equation states that for an incompressible, frictionless fluid, the following sum is constant. The relationship between pressure and velocity in fluids is described quantitatively by Bernoulli's equation:.
