Bernoulli Equation

Apply Bernoulli's principle for fluid flow — pressure, velocity, and height relationships

Fluid Density (kg/m³) Gravity (m/s²)

Point 1

Pressure P₁ (Pa) Velocity v₁ (m/s) Height h₁ (m)

Point 2

Pressure P₂ (Pa) Velocity v₂ (m/s) Height h₂ (m)

Result

P₂ = 100,000 Pa

Constant: 101,325 J/m³

About: Bernoulli's equation states that for an inviscid, incompressible fluid, the total mechanical energy per unit volume remains constant along a streamline: P₁ + ½ρv₁² + ρgh₁ = P₂ + ½ρv₂² + ρgh₂. This principle explains lift in aircraft wings, flow through pipes, and many other fluid phenomena.
