How does the Bernoulli Calculator work?

Enter pressure, velocity, height, and fluid density at two points Then: The calculator applies P₁ + ½ρv₁² + ρgh₁ = P₂ + ½ρv₂² + ρgh₂ Then: Results show energy conservation in fluid flow.

Can you give an example of how to use the Bernoulli Calculator?

Example: Input P₁ = 101.3 kPa, v₁ = 0, z₁ = 0, P₂ = ?, v₂ = 10 m/s, ρ = 1 kg/m³ gives a result of P₂ ≈ 101.3 - 50 = 101.25 kPa (Lower pressure in moving fluid).

Is the Bernoulli Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.

How accurate is the Bernoulli Calculator?

Our Bernoulli Calculator uses verified mathematical formulas and is accurate to multiple decimal places. Results are calculated in real-time using the same methods used by professionals.
