# What is Bernoulli's equation of fluid dynamics?

A:
### Quick Answer

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 P_{1} + ½ρv_{1}^{2} + ρgh_{1} = P_{2} + ½ρv_{2}^{2} + ρgh_{2}, falls in line with the principle of conservation of energy for fluids.

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.

Q:
## How do you calculate the max height equation?

A:The maximum height of a projectile is calculated with the equation h = vy^2/2g, where g is the gravitational acceleration on Earth, 9.81 meters per second, h is the maximum height and vy is the vertical component of the projectile's velocity. If the angle of launch or the velocity of the projectile are not known, these quantities can be derived.
