Bernoulli Equation Calculator
Apply Bernoulli's equation to solve for pressure, velocity, and elevation changes in fluid flow
About this calculator
The Bernoulli Equation Calculator helps engineers and students solve fluid dynamics problems by applying Bernoulli's principle, which relates pressure, velocity, and elevation in flowing fluids. This fundamental equation is essential for analyzing pipe flow, aircraft lift, pumps, and hydraulic systems. The calculator simplifies complex calculations by allowing you to input known values and automatically computing unknown parameters like pressure drops, flow velocities, or elevation changes in fluid systems.
How to use
Enter the known values for pressure, velocity, and elevation at two different points in your fluid system. Select the fluid type or input its density. Choose which unknown parameter you want to calculate. The calculator will apply Bernoulli's equation and provide the result instantly, showing the relationship between energy components in your fluid flow system.
Frequently asked questions
What assumptions does Bernoulli's equation make?
Bernoulli's equation assumes incompressible, inviscid fluid flow along a streamline with steady conditions and no energy losses from friction or turbulence.
When is Bernoulli's equation not applicable?
The equation doesn't apply to compressible flows, viscous flows with significant friction losses, unsteady flows, or flows with heat addition or removal.
What units can I use in the calculator?
The calculator typically supports metric (Pa, m/s, m) and imperial (psi, ft/s, ft) units with automatic unit conversion for consistent results.
