Question

What is the difference between viscous and non-viscous fluid?

Answer 1

Definition

The fluid flow would be a component of fluid mechanics as well as interact with fluid dynamics. It necessitates the flow of a fluid susceptible to uneven forces.

The difference between viscous and non-viscous fluids

Viscous fluids	Non-viscous fluids
1.Fluid travels between neighboring strata without slide-in viscous flow.	1.Eddy currents are produced by the random, irregular, and maybe even unexpected motion of flowing fluid during non-viscous.
2.Viscous flow occurs at low velocity.	2.Non-viscous flow occurs at higher velocities.
3.Shear stresses are modest throughout viscous fluids.	3.Shear stresses are substantially higher in non-viscous flows.

Therefore, the term "vicious" refers to the internal friction of such a fluid. A real "non-viscous" fluid would move along a solid block without even being slowed by friction.
