WebJan 10, 2024 · Bernoulli's principle or Bernoulli's law describes the relationship between pressure and fluid velocity. It states that if the velocity of the fluid is high, the pressure is low. Conversely, if... WebSimplified Bernoulli Equation. Bernoulli's equation results from the application of the general energy equation and the first law of thermodynamics to a steady flow system in which no work is done on or by the fluid, no heat is transferred to or from the fluid, and no change occurs in the internal energy (i.e., no temperature change) of the fluid.

WebBig Ideas: Bernoulli’s principle says that a moving fluid is (in general) at a lower pressure than a still fluid. An airplane stays in the air because of a complex assortment of phenomena, all of which result in the air around a wing being forced downwards. Next: 5.1 – Introduction to Energy and Heat.

"Bernoulli developed his principle from observations on liquids, and Bernoulli's equation is valid for ideal fluids: those that are incompressible, irrotational, inviscid, and subjected to conservative forces. It is sometimes valid for the flow of gases: provided that there is no transfer of kinetic or potential energy from the gas flow to the compression or expansion of the gas. If both the gas pressure and volume change simultaneously, then work will be done on or by the gas. In this cas… " - How does the bernoulli principle work
