The Bernoulli’s equation of fluid dynamics relates pressure, velocity and height at two points in a fluid that is non-viscous, incomprehensible and steady-flowing, according to Boston University. The equation, which is stated as P1 + ½ρv12 + ρgh1 = P2 + ½ρv22 + ρgh2, falls in line with the principle of conservation of energy for fluids.Know More
Bernoulli’s effect implies that when the fluid pressure is lowered, the flow of velocity increases. When the flow of the fluid is constricted, its kinetic energy increases as the pressure reduces. It is difficult to calculate real-world fluid pressure through a constricted flow because of viscous deficits and turbulence.
Science Kids explains how Bernoulli’s effect applies in flying aircraft; the wings of a plane are shaped such that air flowing over them travels faster, while the current underneath is slower. Fast moving air results in low pressure over the wing, and slow moving air causes higher pressure under the wing. The higher pressure underneath the aircraft gives it an upward lift. Paper airplanes obey the same principle.
The way a curveball curves is in line with Bernoulli’s equation. As the ball is thrown to spin, its seams cause slower airflow on one side and faster airflow on the opposite side. The ball is deflected towards the side where the airflow is faster and pressure is lower.Learn more about Chemical Equations
The Rydberg Equation, or Rydberg Formula, predicts the light wavelength that results from the motion of an electron between an atom's different energy levels. Electron movement from one atomic orbital to another changes the energy of that electron.Full Answer >

Fe2O3, or rust, is iron oxide formed by a redox reaction of iron and oxygen in the presence of water. Iron is the reducing agent, as it gives up electrons, while oxygen is the oxidizing agent gaining electrons. Simply expressed, Fe plus H2O plus O2 yields Fe2O3.Full Answer >
The chemical equation for wine fermentation when starting from glucose is C6H12O6 = 2CO2 + 2CH3CH2OH, and when starting from maltose or sucrose, it is C12H22O11 = 4CO2 + 4CH3CH2OH. In both processes, the products are carbon dioxide and ethyl alcohol. Yeast cells are used in the fermentation process to extract energy from the sugar.Full Answer >
