Bernoulli’s principle: along a streamline, p + ½ρv² is constant. Squeeze the flow through a narrow throat and it speeds up (continuity), so its pressure drops. This is how carburetors, atomizers, and airplane wings work. Educational tool.

Throat velocity5.00 m/s

Pressure change-10.50 kPa

Throat pressure89.5 kPa

Governing equation

p + \frac{1}{2} ρ v^{2} + ρ g h = const \Rightarrow Δ p = \frac{1}{2} ρ (v_{1}^{2} - v_{2}^{2}) = - 10.50 kPa

Reading this result: Continuity pushes the fluid through the 2.5× narrower throat, speeding it from 2.0 to 5.0 m/s; Bernoulli’s constant p + ½ρv² then makes the throat pressure drop by 10.50 kPa — faster flow always sits at lower pressure.
