Bernoulli's principle can be derived from the principle of conservation of energy. This states that, in a steady flow, the sum of all forms of energy in a fluid is the same at all points that are free of viscous forces. This requires that the sum of kinetic energy, potential energy and internal energy remains constant.
Learn how Bernoulli's principle states that higher speed regions have lower pressure in a horizontal fluid flow. See how Bernoulli's equation relates pressure, speed, and height of any two points in a steady streamline fluid.
- Hmm, sorry it was confusing. If other people feel the same way I'll rewrite it. As for the steady flow question, the water molecules have randomly...
- Fluids exert pressure in all directions. So the parts of the fluid on the left (P1) of the highlighted region are exerting a pressure on the highli...
- Pascal's Principle applies to fluids that are initially static. In this case, we have a dynamic fluid whose motion is being analyzed...hope that ma...
- Since Bernoullis theorem proved that for a horizontally flowing fluid without the height, the P+1/2*ρv^2 is constant, if the velocity is possessed...
- Gravity is not negative or positive, it's just downward. If you define down as the positive direction, g is 9.8 m/s^2. If you define up as positive...
- The numbers in the last question do add up: P1=601229.01 Pa
- this is due to the pressure energy...at the constriction, pressure energy decreases so kinetic energy increases

Dec 10, 2017 · Learn about Bernoulli’s principle, which states that the total mechanical energy of a moving fluid remains constant. Find out how to derive Bernoulli’s equation, apply it to different situations, and solve problems with examples and FAQs.
Feb 20, 2022 · Explain how to derive Bernoulli’s principle from Bernoulli’s equation. Calculate with Bernoulli’s principle. List some applications of Bernoulli’s principle. When a fluid flows into a narrower channel, its speed increases. That means its kinetic energy also increases.
Bernoulli’s theorem, in fluid dynamics, relation among the pressure, velocity, and elevation in a moving fluid (liquid or gas), the compressibility and viscosity of which are negligible and the flow of which is steady, or laminar. It was first derived in 1738 by the Swiss mathematician Daniel Bernoulli.
