Bernoulli's Principle

$P + \frac{1}{2} \rho v^2 + \rho gh =$ constant

Bernoulli's equation relates the pressure, kinetic energy per unit volume, and potential energy per unit volume of a fluid along a streamline.

Terms:

Pressure energy per unit volume

$\rho$

Density of the fluid

kg/m^3v

Velocity of the fluid

m/sg

Acceleration due to gravity

m/s^2h

Height above a reference point

Bernoulli's principle states that for an incompressible, non-viscous fluid flowing in a streamline, the sum of the pressure energy, kinetic energy, and potential energy per unit volume remains constant.

Common Use:

Used to explain the working of devices like the venturi meter and to understand fluid flow in various applications.
