In
fluid mechanics,
Bernoulli's Equation describes the behavior of moving
fluids along a
streamline.
- <math> {v^2 \over 2}+gy+{P \over \rho}=constant </math>
- v = fluid velocity along the streamline
- g = gravitional constant
- y = elevation in g-field
- P = pressure along the streamline
- ρ = fluid density
These assumptions must be met for the equation to apply:
- Inviscid flow - Viscosity (internal friction) = 0
- Steady flow
- Incompressible flow - ρ is constant
- The equation applies along a streamline.
The equation can be derived by integrating Euler's equation[?] along a streamline.
