Fluid mechanics- It is study of fluids either in
motion or rest.
Fluid- a fluid is a substance that is having ability to flow or deform under the action of shear force.

Mechanics – it is the study of application of load and its effect on machine , fluid , structure etc.

Difference b/w solid and fluid deformation

Deformation w.r.t. time
Removal of load
Type of deformation
Type of load

Fluid as Continuum
Fluids are aggregations of molecules; widely spaced for a gas and closely spaced for liquids. Distance between the molecules is very large compared to the molecular diameter. The number of molecules involved is immense and the separation between them is normally negligible. Under these conditions, fluid can be treated as continuum and the properties at any point can be treated as bulk behavior of the fluids
