  2. Venturi effect - Wikipedia

    en.wikipedia.org/wiki/Venturi_effect

    The Venturi effect is the reduction in fluid pressure that results when a moving fluid speeds up as it ... using Bernoulli's equation in the special case of steady ...

  3. Bernoulli's principle - Wikipedia

    en.wikipedia.org/wiki/Bernoulli's_principle

    Although Bernoulli deduced that pressure decreases when the flow speed increases, it was Leonhard Euler in 1752 who derived Bernoulli's equation in its usual form. [4] [5] Bernoulli's principle can be derived from the principle of conservation of energy. This states that, in a steady flow, the sum of all forms of energy in a fluid is the same ...

    en.wikipedia.org/wiki/Choked_flow

    Accidental release source terms includes mass flow rate equations for non-choked gas flows as well. Orifice plate includes derivation of non-choked gas flow equation. de Laval nozzles are venturi tubes that produce supersonic gas velocities as the tube and the gas are first constricted and then the tube and gas are expanded beyond the choke plane.

    When the air flows through the tube, there is a lower pressure in narrower tube section and this value is independent from the end from which the air is introduced. In the area where the pipe diameter is smaller, the air flow in fact has greater speed, which results in a lower pressure in accordance with Bernoulli's equation.

  6. Vacuum ejector - Wikipedia

    en.wikipedia.org/wiki/Vacuum_Ejector

    A vacuum ejector, or simply ejector, or aspirator, is a type of vacuum pump, which produces vacuum by means of the Venturi effect.. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.

  7. Siphon - Wikipedia

    A venturi siphon, also known as an ... As the siphon is a single system, the constant in all four equations is the same. Setting equations 1 and 4 equal to each other ...

    en.wikipedia.org/wiki/Parshall_flume

    These final two equations are very similar to the Q = CH a n equations that are used for Parshall flumes. In fact, when looking at the flume tables, n has a value equal to or slightly greater than 1.5, while the value of C is larger than (3.088 b 2 ) but still in a rough estimation.

  9. Dynamic pressure - Wikipedia

    en.wikipedia.org/wiki/Dynamic_pressure

    Dynamic pressure is one of the terms of Bernoulli's equation, which can be derived from the conservation of energy for a fluid in motion. [1] At a stagnation point the dynamic pressure is equal to the difference between the stagnation pressure and the static pressure, so the dynamic pressure in a flow field can be measured at a stagnation point ...
