Which word do you not understand?
incompressible - cannot be compressed
viscous - resistant to flow, "thick"
fluid - substance that flows (both gases and liquids are fluids, but gases are usually compressible; liquids generally aren't)
In an incompressible fluid, the velocity field describes how the fluid moves without changing its density.
The key assumptions underlying the Navier-Stokes equations are that the fluid is continuous, incompressible, and viscous. These equations also assume that the flow is steady and that the forces acting on the fluid are balanced.
compression in fluids changes the volume of fluid whereas the volume isinversely proportional to the the kinetic energy of flowing fluid. viscous nature of fluid is due to cohesion and adhesion forces of the fluid hence these forces regulates the speed of flowing fluid on the walls of pipe and within the fluid molecules.
An incompressible fluid is a substance that does not change its volume when subjected to pressure. It has constant density and is not easily compressed. Incompressible fluids flow smoothly and exhibit properties such as high viscosity and low compressibility.
The basic assumption inherent in Darcy's law is that the flow of fluid through a porous medium is proportional to the pressure gradient in the direction of flow. This assumes that the fluid is flowing through a homogeneous and isotropic medium.
Ideal Fluid:An incompressible fluid that has no internal viscosity.

The density of a compressible fluid changes with pressure, while the density of an incompressible fluid is not affected by pressure (assuming isothermal conditions).

if the density of the fluid changes with respect to pressure is called compressible fluid f the density of the fluid does not changes with respect to pressure is called incompressible fluid
The basic assumption inherent in Darcy's law is that the flow of fluid through a porous medium is proportional to the pressure gradient in the direction of flow. This assumes that the fluid is flowing through a homogeneous and isotropic medium.
In incompressible fluid density is same because velocity gradient is same on every layer of liquid at any cross section.
More viscous refers to a fluid's resistance to flowing. A higher viscosity indicates a thicker or more sluggish fluid that flows more slowly. Examples of more viscous substances include honey and molasses.
