Fluid Mechanics is the branch of physics that deals with the behaviour of fluids (liquids, gases, and plasmas) and the forces on them. Fluid mechanics can be divided into two subfields fluid statics, which studies fluids at rest; and fluid dynamics, which studies fluids in motion. Fluid mechanics is based on several mathematical relationships that describe the kinematics, stress, conservation, regulation, and constitutive properties of fluids.

Hydraulic Machines are defined as those machines which convert either hydraulic energy (energy possessed by water) into mechanical energy (which is further converted into electrical energy ) or mechanical energy into hydraulic energy. The hydraulic machines, which convert the hydraulic energy into mechanical energy, are called turbines while the hydraulic machines which convert the mechanical energy into hydraulic energy are called pumps.
