Understanding how a moving fluid's speed and pressure change as it flows along is not only important for building airplanes but also for backyard. Looking for bernoulli's principle find out information about bernoulli's principle physical principle formulated by daniel bernoulli that states that as the speed of a moving fluid increases, the pressure within the fluid decreases explanation of bernoulli's principle. This is the first of two videos where sal derives bernoulli's equation.
To understand bernoulli's principle, it helps to think of air as a bunch of tiny balls. Some real-world examples of bernoulli's principle are the upward lift exerted upon the wings of airplanes gliders and birds, the upward pressure that enables liquids to be ejected from atomizers, the.
