The Navier-stroke equation was proposed by French engineer and physicist Claude-Louis Navier and George-Gabriel Strokes. The Navier-Stroke equation is composed of a partial differential equation which tells about the motion of the viscous fluid.

This equation follows the law of conservation of mass and conservation of momentum. As it describes the motion of fluid it is also stated as Newton's second law of motion for fluids. For a compressible Newtonian fluid, this yields

where u represent the fluid velocity

p is fluid pressure,

ρ is the fluid density and

μ is the fluid dynamic viscosity.
