Bernoulli equation [ber‚nü·lē i′kwā·zhən]
(fluid mechanics) (mathematics) A nonlinear first-order differential equation of the form (dy/dx) +yf(x) =yng(x), wherenis a number different from unity andfandgare given functions. Also known as Bernoulli differential equation. Bernoulli Equation a differential equation of the first order of the form dy/dx + Py = Qyα where P and Q are predetermined continuous functions of x and α is a constant. With the introduction of the new function z = y-α + 1, the Bernoulli equation is reduced to a linear differential equation with respect to z. The Bernoulli equation was considered by Jakob Bernoulli in 1695, and a method of solving it was published by Johann Bernoulli in 1697. Want to thank TFD for its existence?
