Key Fluid Properties Explained

Density

The mass per unit volume of a fluid. It varies significantly with temperature, especially for gases, affecting pressure drop and flow rate calculations.

Dynamic vs. Kinematic Viscosity

  • Dynamic Viscosity : A measure of a fluid’s internal resistance to flow.

  • Kinematic Viscosity : The ratio of dynamic viscosity to density, essential for determining the flow regime (Laminar vs. Turbulent).

Specific Heat

Crucial for HVAC engineers designing chilled water or hot water systems to determine the energy carrying capacity of the fluid.

FAQ

  1. Q: Why does water density decrease as temperature rises? A: As temperature increases, molecules move faster and take up more space, leading to a decrease in mass per unit volume.
  2. Q: What is the importance of Viscosity in pipe sizing? A: Viscosity directly affects the Reynolds Number; higher viscosity leads to higher friction loss and requires larger pump heads.
  3. Q: What properties does the application cover? Density, Specification Volume, Specific Enthalpy, Specific Entropy, Specific Heat, Thermal Conductivity, Dynamic Viscosity, ….. etc
  4. What can I do with this calculator? You can get properties of fluid (Water, air, gases, Liquids,….) at specific temperature and pressure. You can get saturation liquid and saturation vapour at specific conditions.
