Summary
This section covers fundamental principles of fluid dynamics, beginning with the definition and calculation of flow rate, moving into the continuity equation for incompressible fluids, and exploring Bernoulli's equation which relates pressure, velocity, and height in an energy conservation framework. It further delves into viscosity, laminar flow, and Poiseuille’s law, showcasing how small changes in tube radius can drastically alter flow rates. Moreover, by introducing the Reynolds number, the text explains how to differentiate between laminar and turbulent flows, and finally discusses molecular transport phenomena including diffusion, osmosis, and active transport. Together, these topics form the basis for understanding fluid behavior in both natural and technological systems.
