Synthesis on Fluid Mechanics Concept
Fluid mechanics is a branch of physics concerned with the behavior of fluids (liquids and gases)
at rest (Fluid Statics) and in motion (Fluid Dynamics). Fluid mechanics is a branch of
continuous mechanics which deals with a relationship between forces, motions, and statical
conditions in a continuous material. A fluid is a substance which deforms continuously under the
application of a shear stress. A Shear stress is defined as a force per unit area, acting parallel to
an infinitesimal surface element. We have a normal stress which is the pressure and tangential
stress which is the shear stress.
The principles of fluid mechanics underpin diverse application such as hydrodynamics,
hydraulics, aerodynamics, and gas dynamics, enabling the design of infrastructure, vehicles,
and tools. By analyzing how fluids respond to forces, fluid mechanics provides insights essential
for advancing technology and understanding the environment.
Any characteristic of a system is called a property. Some of these properties are pressure P,
temperature T, volume V, and mass m. Properties are considered to be either intensive or
extensive properties. Extensive property per unit mass is known as specific property and some
example of specific property are specific volume (v=V/m) and specific total energy (e=E/m).
