The Bernoulli Equation

The Bernoulli Equation describes how the speed, pressure, and height of a fluid relate to each other in steady flow. It states that in a flowing fluid, when the fluid speeds up, its pressure decreases, and when it slows down, pressure increases, assuming no energy is added or lost. Think of it like a river: where it narrows, water speeds up and pressure drops; where it widens, water slows and pressure rises. This principle helps explain many real-world phenomena, like airplane lift and blood flow.
