This document discusses properties of fluids and fluid statics. It defines a fluid and fluid mechanics, and classifies fluids as real or ideal. Physical properties of fluids discussed include mass density, specific weight, specific volume, relative density, viscosity, and surface tension. Viscosity is defined using Newton's law of viscosity. Fluid statics is the study of fluids at rest, and concepts covered include pressure, Pascal's law, manometers, buoyancy, and pressure on surfaces. Key terms are defined such as specific gravity, specific volume, and the relationships between mass density, specific weight, and viscosity.
