Lesson 4: Fluid Dynamics and Bernoulli's Principle
Duration of Days: 3
Lesson Objective
Apply the continuity equation and Bernoulli’s equation to analyze fluid flow, demonstrating that as fluid velocity increases, its internal pressure simultaneously decreases.
Why does water shoot out much faster and more violently when you place your thumb over the end of a garden hose?
How do the massive, heavy wings of a commercial airplane generate the physical lift required to fight gravity and take off?
If a moving fluid speeds up as it travels through a narrow pipe constriction, does the pressure inside that constriction go up or down?

HS-PS3-2: Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motions of particles and energy associated with the relative position of particles. (Applied to Bernoulli's Principle and fluid flow).
To move from studying static fluids to fluids in motion (hydrodynamics) and modeling the conservation of energy in continuous fluid streams.
How hurricanes rip roofs off houses: During a severe hurricane, high-speed winds blow rapidly across the top of a house's roof. According to Bernoulli's principle, this extreme velocity creates a zone of incredibly low pressure directly above the roof. Meanwhile, the air trapped inside the house remains stagnant, maintaining standard, high atmospheric pressure. This dramatic pressure differential creates a massive upward net force, lifting and blowing the roof right off the house from the inside out.
