Bernoulli Equation Calculator — Solve Pressure, Velocity & Height

Solve for an unknown pressure, velocity, or height term in a flowing fluid using the Bernoulli equation. Analyze pipe and duct systems.

Fluid Velocity (m/s)
Pipe Diameter (m)
Kinematic Viscosity ν (m²/s)
Common ν: Water 20°C = 1.004×10⁻⁶ · Air 20°C = 1.516×10⁻⁵ m²/s
⟨∿⟩ Fluids Reference: All calculations use SI units (Pa, m³/s, W, K). Moody friction factor uses Blasius smooth-pipe approximation. Bernoulli assumes ideal, incompressible, steady flow along a streamline.

How It Works

Solve for an unknown pressure, velocity, or height term in a flowing fluid using the Bernoulli equation. Analyze pipe and duct systems

Each component has a specific meaning:

  • Bernoulli equation — The bernoulli equation recorded for the patient or scenario being assessed.

Note: Interpret the bernoulli equation result against the clinical thresholds and context described above.

How to Use

Enter the Bernoulli equation for the patient or scenario you are assessing. Solve for an unknown pressure, velocity, or height term in a flowing fluid using the Bernoulli equation. Analyze pipe and duct systems. Use the bernoulli equation result to inform your clinical assessment.
