MECHANICS OF FLUIDS
BSCE 3A/3B
2.FLUID PROPERTIES
LEARNING OUTCOMES:
• Define fluid properties
• Solve problems involving properties of fluids
•
DISCUSSION:
Property: Any characteristic of a system.
Some familiar properties are pressure P, temperature T, volume V, and mass m.
Properties are considered to be either intensive or extensive.
• Intensive properties: Those that are independent of the mass of a system, such as temperature,
pressure, and density.
• Extensive properties: Those whose values depend on the size— or extent—of the system.
• Specific properties: Extensive properties per unit mass.
These properties can be broadly categorized under:
• Kinematic properties: These properties help in understanding the fluid motion. Velocity and
acceleration are the kinematic properties of the fluids.
• Thermodynamic properties: These properties help in understanding the thermodynamic state of
the fluid. Temperature, density, pressure, and specific enthalpy are the thermodynamic
properties of the fluids.
• Physical properties: These properties help in understanding the physical state of the fluid such
as color and odor.
