(Fluid Dynamics from Hoses to Propellers)

This episode is a full master class in fluid mechanics, built to change the way you see the physical world. From garden hoses and Roman aqueducts to airplane wings, golf balls, hydraulic jumps, and ship propellers ripped apart by collapsing vapor bubbles, we break down the hidden rules that govern how fluids actually behave.

We start with the ideal world of frictionless flow and build the foundation with the continuity equation and Bernoulli’s equation. Learn how area, velocity, and pressure trade energy inside a fluid, why putting your thumb over a…
