    Fluid Properties

    14.1 : Characteristics of Fluids01:31

    14.1 : Characteristics of Fluids

    Fluids differ from solids mainly in their molecular structure and stress response. Solids have tightly packed molecules with strong intermolecular forces, ...

    14.2 : Density, Specific Weight, Specific Gravity and Compressibility of Fluid01:27

    14.2 : Density, Specific Weight, Specific Gravity and Compressibility of Fluid

    The density of a fluid, defined as mass per unit volume, determines key fluid properties such as buoyancy, pressure distribution, and flow behavior. For ...

    14.3 : Viscosity of Fluid01:19

    14.3 : Viscosity of Fluid

    Viscosity measures how a fluid resists flowing due to internal friction when layers of the fluid move past each other. For example, honey flows slowly ...

    14.4 : Types of Fluids01:27

    14.4 : Types of Fluids

    Fluids are classified into two main types: Newtonian and non-Newtonian. Newtonian fluids have a constant viscosity, and their shearing stress is linearly ...

    14.5 : Newtonian Fluid: Problem Solving01:18

    14.5 : Newtonian Fluid: Problem Solving

    A Newtonian fluid has a constant viscosity, meaning the shear stress is directly proportional to the rate of shear strain. This behavior ensures the fluid ...

    14.6 : Vapor Pressure of Fluid01:28

    14.6 : Vapor Pressure of Fluid

    The vapor pressure, which influences boiling and cavitation, is the pressure exerted by a vapor in equilibrium with its liquid at a given temperature and ...

    14.7 : Surface Tension of Fluid01:22

    14.7 : Surface Tension of Fluid

    A steel needle or a razor blade can float on water if placed gently due to surface tension, which arises at the interface between a liquid and a gas or ...

    14.8 : Capillarity in Fluid01:19

    14.8 : Capillarity in Fluid

    Capillarity refers to the movement of liquid in narrow spaces, driven by surface tension and adhesive forces between the liquid and nearby surfaces. Such ...

    14.9 : Design Example: Deciding Thickness of Lubricating Fluid in a Shaft01:23

    14.9 : Design Example: Deciding Thickness of Lubricating Fluid in a Shaft

    A rotating shaft operates inside a bearing housing. The shaft rotates at a specific speed and supports a load, requiring a lubricant with the correct ...
