Question

what's Bernoulli 's theorem..?

Answer 1

In fluid dynamics, Bernoulli's principle states that "an increase in the speed of a fluid occurs simultaneously with a decrease in Pressure or a decrease in the fluids potential energy".

The principle is named after DANIEL BERNOULLI who published it in his book HYDRODYNAMICA in 1738

Answer 2

Hey there!

Thank you for your Question!

Bernoulli's theorem:

The Bernoulli's theorem states that for an ideal fluid, under steady state condition, the sum of kinetic energy per unit volume, potential energy per unit volume (or sum of mechanical energy per unit volume) and pressure per unit volume is constant.

Equation of Bernoulli's theorem:

$\huge{{{\boxed{\boxed{\bold{\frac{\rho v^2}{2}+\rho gh + P = Constant}}}}$

$\\\textbf{where,}\\\bold{\rho} =\textbf{Density of fluid}\\P = \textbf{Pressure}\\v = \textbf{Velocity of fluid in section.}\\g =\textbf{Acceleration due to gravity}\\h = \textbf{Height in the direction of gravity}$
