Question

Explain Bernoulli's Theorem.

Answer 1

Answer:

Alternative Titles: Bernoulli’s law, Bernoulli’s principle

Bernoulli’s theorem, in fluid dynamics, relation among the pressure, velocity, and elevation in a moving fluid (liquid or gas), the compressibility and viscosity (internal friction) of which are negligible and the flow of which is steady, or laminar. First derived (1738) by the Swiss mathematician Daniel Bernoulli, the theorem states, in effect, that the total mechanical energy of the flowing fluid, comprising the energy associated with fluid pressure, the gravitational potential energy of elevation, and the kinetic energy of fluid motion, remains constant. Bernoulli’s theorem is the principle of energy conservation for ideal fluids in steady, or streamline, flow and is the basis for many engineering applications.

Answer 2

Answer:

hey dear ❤

Influid dynamics , Bernouli's priciple states that an increase in the speed of fluid occurs simultaneously with the decrease in pressure or a decrease in the fluid potential energy. The principle named after Daniel Bernouli who published it in his book Hydronomica in 1738.
