How to solve a bernoulli equation.
The brachistochrone problem was one of the earliest problems posed in the calculus of variations. Newton was challenged to solve the problem in 1696, and did so the very next day (Boyer and Merzbach 1991, p. 405). In fact, the solution, which is a segment of a cycloid, was found by Leibniz, L'Hospital, Newton, and the two Bernoullis.
Bernoulli's equation is a special case of the general energy equation that is probably the most widely-used tool for solving fluid flow problems. It provides an easy way to relate the elevation head, velocity head, and pressure head of a fluid. It is possible to modify Bernoulli's equation in a manner that accounts for head losses and pump work. 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 ...Under that condition, Bernoulli’s equation becomes. P 1 + 1 2ρv12 = P 2 + 1 2ρv22 P 1 + 1 2 ρ v 1 2 = P 2 + 1 2 ρ v 2 2. Situations in which fluid flows at a constant depth are so important that this equation is often called Bernoulli’s principle. It is Bernoulli’s equation for fluids at constant depth.native approaches which do not rely on Bernoulli Equation must solve for V~ (x,y,z) and p(x,y,z) simultaneously, which is a tremendously more difficult problem which can be ap-proached only through brute force numerical computation. Venturi flow Another common application of the Bernoulli Equation is in a venturi, which is a flow tube
