Question

Define Bernouli’s statement. Illustrate it with an experiment.​

Answer 1

In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy. The principle is named after Daniel Bernoulli who published it in his book Hydrodynamica in 1738

Bernoulli’s equation formula is a relation between pressure, kinetic energy, and gravitational potential energy of a fluid in a container.

The formula for Bernoulli’s principle is given as:

p + 12 ρ v2 + ρgh =constant

Where,

p is the pressure exerted by the fluid

v is the velocity of the fluid

ρ is the density of the fluid

h is the height of the container

Bernoulli’s equation gives great insight into the balance between pressure, velocity and elevation.

Answer 2

Answer:

State and prove Bernoulli’s theorem.

Answer

 Here, we first know what Bernoulli's principle states, and then further we can prove the theorem by deriving the expression which relates the pressure and potential energy of the fluid. At last we will also note down the limitations of this theorem.

Formula used:

K.Egained=12ρ(v22−v12)P.
