Question

Explain Bernoulli's Principle.

Answer 1

Bernoulli's Principle:

1. According to Bernoulli's principle, The total mechanical energy of the moving fluid, which includes gravitational potential energy of elevation, fluid pressure energy, and kinetic energy of fluid motion, remains constant.
2. Bernoulli's principle is derived from the principle of energy conservation.
3. Bernoulli's equation sheds light on the relationship between pressure, velocity, and elevation.

The formula for Bernoulli’s principle is given:

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

Where,

$P$ is the pressure exerted.

$v$ is the velocity of the fluid.

$\rho$ is the density of the fluid.

$h$ is the height of the container.
