The "Science of Fluids" studies the behavior of liquids and gases, focusing on their properties and how they interact with forces. This field encompasses various principles, such as hydrodynamics, which examines fluid motion, and thermodynamics, which looks at heat transfer in fluids. Understanding these concepts is essential for applications in engineering, meteorology, and environmental science. Fluid mechanics, a key area within the science of fluids, explores how fluids flow and the forces acting on them. It includes topics like viscosity, which measures a fluid's resistance to flow, and Bernoulli's principle, which explains how pressure changes in moving fluids. These principles help design systems like pipelines and aircraft.
