  Definition of a Fluid

  • What is a fluid?

    * Substances that deform continuously under shear stress.
    * Includes both liquids and gases.

  • Key Physical Properties

  Below are the fundamental physical properties every fluid technician, student, or engineer should understand:

  a. Density (ρ)

  * Mass per unit volume (kg/m³).
  * Importance: Affects buoyancy, pressure calculations, and fluid dynamics.

  b. Specific weight (ω)

  *Defined as the weight per unit volume at the standard temperature and pressure

  c. Specific volume (υ)

  *defined as volume per unit of fluid.​

   *S.I unit is m³/kg

  d. Viscosity (μ)

  * Measure of fluid resistance to flow.

  1. Dynamic Viscosity (Pa·s)
  2. Kinematic Viscosity (m²/s)

  * Affects laminar or turbulent flow characteristics.

  e. Pressure (P)

  * Force per unit area (Pa or N/m²).
  * Types: Atmospheric, gauge, absolute, and vapor pressure.

  f. Temperature (T)

  * Influences most other physical properties (viscosity, density, surface tension).
  * Units: °C, K

  g. Specific Gravity (SG)

  * Ratio of fluid density to that of water (dimensionless).

  h. Compressibility (β)

  * Change in volume under pressure.
  * Gases: Highly compressible
  * Liquids: Nearly incompressible

  Measurement Techniques

  Devices used:

  • Hydrometer (Density)
  • Viscometer (Viscosity)
  • Manometer or Pressure Transducer (Pressure)
  • Thermocouple or Thermometer (Temperature)

  Applications

  • Engineering (pipe flow, pumps, turbines)
  • Medicine (blood flow, IV drips)
  • Environmental science (air and water quality)
  • Industrial processes (mixing, heat exchange)
