that make this field so relevant to our lives What are Fluids First we need to define what we mean by a fluid In fluid mechanics both liquids and gases are considered fluids This might seem counterintuitive at first but the defining characteristic of a fluid is its ability to deform continuously under the application of a shear stress This means that fluids will flow and change shape to accommodate external forces Key Concepts in Fluid Mechanics Here are some core concepts that form the foundation of fluid mechanics Density Density is the mass per unit volume of a fluid This property plays a crucial role in determining how a fluid will behave under different forces Pressure Pressure is the force exerted per unit area Fluids exert pressure in all directions due to the collisions of their constituent particles Viscosity Viscosity measures a fluids resistance to flow Think of honey versus water honey is more viscous and flows more slowly Buoyancy Buoyancy is the upward force exerted on an object submerged in a fluid This force is directly related to the density of the fluid and the volume of the object submerged Surface Tension Surface tension is the force that holds a liquids surface together creating a skin that resists being broken Flow Rate Flow rate is the volume of fluid passing through a given point per unit time 2 The Tools of the Trade Understanding how
