As F= 16/Nre.
And Nre= density*v*l/viscosity.
So it depend on length and not depend upon mass flow rate.
And Nre= density*v*l/viscosity.
So it depend on length and not depend upon mass flow rate.

If we keep eyes on formula there is length in it. So how can you say that it does not depend on length.

@Laxman.
When the length increases friction losses increase. But f is independent of length.

F depends upon Re and Re doesn't depend upon length and roughness depend upon dia only so A.

But one Formula says that it depends on length.
dh = (4*f)* (l/d)* (u2/density*g)
Than...?
dh = (4*f)* (l/d)* (u2/density*g)
Than...?

hfs = (4flv^2)/2d it's simplifies.
f = (hfs*2d)/(lv^2).
f is doesn't depends on l and v.
f = (hfs*2d)/(lv^2).
f is doesn't depends on l and v.

Can someone please explain how friction factor depends on mass flow rate of the fluid?

But as we increase pipe length friction will increase then how option A?

Hence frictional factor is not dependent on length.
