A community portal about Bernoulli's principle with blogs, videos, and photos. According to Wikipedia.org: Bernoulli's principle states that in an ideal fluid, with no work being performed on the fluid, an increase in velocity occurs simultaneously with decrease in pressure or gravitational energy. This principle is a simplification of Bernoulli's equation, which states that the sum of all forms of energy in a fluid flowing along an enclosed path is the same at any two points in that path. It is named after the Dutch / Swiss mathematician/scientist Daniel Bernoulli, though it was previously understood by Leonhard Euler and others. In fluid flow with no viscosity, and, therefore, one in which a pressure difference is the only accelerating force, it is equivalent to Newton's laws of motion. It is important to note that the only cause of the change in fluid velocity is the difference in pressure on either side of it. It is very common for the Bernoulli effect to be quoted as if it states that a change in velocity causes a change in pressure. The Bernoulli principle does not make this statement.
