🌊 Bernoulli Equation Calculator
Use Bernoulli’s Equation to find how fluid pressure changes between two points in a flow, accounting for speed and height differences.
What Bernoulli’s Equation describes
Bernoulli’s Equation expresses conservation of energy for a flowing, non-viscous, incompressible fluid: P1 + ½ρv1² + ρgh1 = P2 + ½ρv2² + ρgh2, where P is pressure, ρ is fluid density, v is flow velocity, h is height, and g is gravitational acceleration, evaluated at two points along the same streamline.
How this calculator works
Enter the fluid’s density along with the pressure, velocity, and height at point 1, plus the velocity and height at point 2. The calculator rearranges Bernoulli’s Equation to solve for the unknown pressure at point 2, showing the result in both pascals and kilopascals.
This idealized equation ignores fluid viscosity and friction losses, so it works best for smooth, steady flow of fluids like water or air over short distances. This calculator is for general physics and engineering education purposes.
