It then presume the friction is very small and presume no friction.
In fluid and piping, it mean any pressure drop term is due to fluid motion and dispersion alone.

Why some friction occur with seemingly smooth surface?
A smooth surface is not actually smooth; it may have many microscopic bumps on its surface.
What surface has the least amount of friction?
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
Is friction is more on smooth surface?
Surface friction is defined as the resistance of an object experiences during motion. So, for the same object, a smooth surface has less friction than a rough surface. Think about skating on ice or a piece of plywood!
What is much friction the smooth surface or the rough?
the rough surface creates more friction as to that of soft surfaced ones
Why is it difficult to walk on smooth and loose surface?
it is because smooth surfaces have less friction so when friction is less it is hard to walk

Does a smooth surface reduce friction?
There is more friction between the surfaces of 2 smooth surfaces than one smooth surface because there is more surface area.

Why is it difficult to strike a match on a smooth surface?
Heat necessary to lit a match comes from friction between match head and the surface. Smooth surface gives way less friction.

Why is there less resistance on a smooth surface?
Because friction is less on smooth surfaces. Smoother the surfaces, lesser the friction.
Why does some friction occur with seeminly smooth surface?
Even though the surface appears smooth.at the microscopic level the surface has some peaks and cracks .when it slides over any other surface friction occurs. the seemingly smooth surface has some friction.
What is it called to smooth a surface to reduce friction?
lubrication
What is much friction the smooth surface or the rough?
the rough surface creates more friction as to that of soft surfaced ones
How does an object move on a rough and on a smooth surface?
It is on smooth surfaces because the amount of friction is less.
Why is it difficult to walk on smooth and loose surface?
it is because smooth surfaces have less friction so when friction is less it is hard to walk
What surface doesn't cause a lot of friction?
A very smooth surface or a smooth surface coated with a liquid, oil or a Teflon like substance.
