What Is The Limit Between A Perfect Fluid And A Real Fluid?

The two types of fluids: ideal, or perfect, fluids and real fluids. An ideal fluid is incompressible, and flow involves no friction. During flow, juxtaposed fluid “layers” experience no tangential stresses, only normal stresses. 

As a consequence, there is no friction between layers and thus no internal resistance to shearing motion, an ideal fluid is inviscid. Real fluid effects are apparent in a region called the boundary layer, a region very close to a body submerged in a fluid flow.
