Distinguish, differentiate, compare and explain what is the difference between viscous and non-viscous flow.

Comparison and Difference between Viscous and Non-viscous Flow

• In viscous flow, fluid moves in adjacent layers without slip. Non-viscous or turbulent flow is characterized by random, erratic, unpredictable motion of fluid particles which results in eddy currents.

• Viscous flow occurs at low velocity while non-viscous occurs at higher velocities.

• In viscous shear stresses are of small magnitude. In non-viscous flow shear stresses are much greater.
