Venturi effect - Wikipedia
The Venturi effect is the reduction in fluid pressure that results when a moving fluid speeds up as it flows through a constricted section (or choke) of a pipe. The Venturi effect is named after its discoverer, the 18th-century Italian physicist Giovanni Battista Venturi.
文丘里效应 - 维基百科，自由的百科全书
文丘里效应 （也称文氏效应， 英語： Venturi effect）。 这种现象以其发现者，意大利物理学家 文丘里 (1746–1822年)命名。 这种效应是指在高速流动的气体附近会产生 压强 减少，从而产生吸附作用。 利用这种效应可以制作出 文氏管。 当气体或液体在 文丘里管 里面流动，因著 連續性方程式 在管道的最窄处，速度达到最大值， 静态压力 达到最小值。 气体（液体）的速度因为涌流横截面积变化的关系而上升。 整个涌流都要在同一时间能经历管道缩小过程，因而压力也在同一 …
Venturi effect: simple explanation and application examples
2024年5月30日 · The Venturi effect is a fluid mechanics phenomenon that occurs when a moving fluid passes through a conical-shaped section of tube, narrowing in the central part and then widening again. This phenomenon was discovered by the Italian physicist Giovanni Battista Venturi at the end of the 18th century and has since been of great importance in ...
Venturi Effect | Principles, Applications & Analysis
2024年5月29日 · The Venturi Effect is a fundamental principle in fluid dynamics, observed when a fluid flows through a constricted section of a pipe or channel. This phenomenon is named after Giovanni Battista Venturi, an 18th-century Italian physicist, who first described the relationship between the velocity and pressure of fluids in motion.
The Venturi Effect explained - Mechanical Engineering
2019年12月2日 · The Venturi Effect goes against the natural assumption that pushing fluid through a restricted pipe increases pressure when in reality the increase in velocity leads to a reduction in pressure. The Venturi Effect was discovered by Italian physicist Giovanni Battista Venturi who lived between 1746 and 1822.
解密 Venturi 效应的奥秘：简化流体动力学 - formulas.today
文丘里效应是一种现象，当流体通过管道或通道的收缩部分时，流速增加而压力降低。 简单来说，当你挤压水管的一部分，水流出得更快时，你正在目睹文丘里效应的作用。 代表文丘里效应的核心公式是： 为了彻底理解，让我们分解每个组成部分： ΔP (压差): 这是管道中两个点之间的压力差，通常以帕斯卡 (Pa) 为单位。 例如，如果收缩部分前的压力为 5000 Pa，收缩部分后的压力为 2000 Pa，则 ΔP 为 3000 Pa。 ρ (密度): 计算需要流体的密度。 这是流体每单位体积的质量。 …
Venturi effect: Definition, Applications - Science Info
2023年6月12日 · The Venturi effect is the decrease in fluid pressure that occurs when a fluid passes through a constrained segment. A pitot tube, a horizontal tube with an IJ-shaped tube within, is used to calculate the velocity of a fluid moving through it.
The Venturi effect. What it is and its application fields
The so-called “Venturi effect” is a physical principle according to which a fluid that moves inside a conduit increases or decreases its pressure according to its speed. This characteristic was discovered in the 19th century by the Italian physicist Giovanni Battista Venturi , during some research on fluid mechanics, and it is still used ...
Venturi effect - tec-science
2020年6月14日 · The Venturi Effect refers to the decrease of static pressure in flowing fluids with increasing flow velocity due to energy conservation! The Venturi effect can be demonstrated impressively on a vertical tube mounted on a plate with a hole.
What Is the Venturi Effect in Fluid Flow? - Thermal Engineering
2024年5月25日 · The Venturi effect is a fundamental and applied principle in fluid dynamics that describes how the velocity of a fluid increases as it passes through a constricted section of a pipe. This principle is named after the Italian physicist Giovanni Battista Venturi, who discovered the phenomenon in the late 18th century.
