Formula

P₁ + ½ρv₁² = P₂ + ½ρv₂².

P₂ = P₁ + ½ρ(v₁²−v₂²).

How to Use

  1. Enter density, two speeds and reference pressure.
  2. It returns pressure P₂.

Case Studies

ρ=1000, v₁=1, v₂=3, P₁=101325 → P₂=97325 Pa

P₂ = 101325 + 0.5·1000·(1−9) = 97325 Pa.

FAQ

Why lower pressure at higher speed?

Bernoulli: higher dynamic pressure means lower static pressure in the constricted section.
