![]() Whether for producing a flow meter, a vacuum system. This interface is used to calculate a venturi according section, density, flow or pressure measured. The calculation interface Venturi tube in tools MECAFLUX Passage through the narrowing, the fluid velocity, so its kinetic energy should be increased at the expense of pressure energy.Īssuming that the flow is laminar, the major pressure losses of the duct are negligible, and that the speed is the average speed: ![]() ![]() This decrease in pressure in a narrowing of the duct may seem contradictory, unless you consider the pressure as an energy density. The Bernoulli equation can be considered as a principle of conservation of energy, suitable for moving fluids.The behavior usually called "Venturi effect" or "Bernoulli effect" is the reduction of fluid pressure in areas where the flow velocity is increased. ![]()
