    Pressure Measurement and Hydrostatic Pressure

    • Technical terms used in Hydraulics:
      • Fluid - A substance that deforms continuously under applied shear stress.
      • Fluid Mechanics - The study of fluids and their behavior.
      • Hydraulics - The study of fluids at rest or in motion.
      • Hydrostatics - The study of fluids at rest.
      • Hydrodynamics - The study of fluids in motion.
      • Ideal Fluid - Incompressible, inviscid, and non-turbulent fluid.
      • Real Fluid - Possesses viscosity and compressibility, and can be turbulent.
    • Physical Properties of Fluid:
      • Density - Mass per unit volume.
      • Specific Volume - Volume per unit mass.
      • Specific Gravity - Ratio of density of fluid to density of water.
      • Vapor Pressure - The pressure exerted by the vapor of a liquid in equilibrium with its liquid.
      • Surface Tension - Force per unit length acting perpendicular to a line drawn on the surface.
      • Capillarity - The rise or fall of liquid in a narrow tube due to surface tension.
      • Viscosity - Resistance to flow.
        • Newton's Law of Viscosity - The shear stress is proportional to the rate of strain.
        • Dynamic Viscosity - Viscosity of a fluid.
        • Kinematic Viscosity - Dynamic viscosity divided by density.
    • Various Types of Pressure:
      • Atmospheric Pressure - The pressure exerted by the atmosphere.
      • Gauge Pressure - The difference between absolute pressure and atmospheric pressure.
      • Absolute Pressure - The total pressure exerted by a fluid.
      • Vacuum Pressure - Absolute pressure below atmospheric pressure.
    • Concept of Pressure Head - Equivalent height of a column of fluid that exerts the same pressure. Measured in meters.
    • Pascal's Law - Pressure applied at any point in an enclosed fluid is transmitted undiminished to every point within the fluid. Applications include hydraulic systems and presses.
    • Measurement of Differential Pressure:
      • Manometers - Devices used to measure pressure differences.
        • Piezometer - A simple manometer consisting of a vertical tube open at the top. Has limitations in measuring pressure.
