State Stoke’s law.
Stoke’s law states that the viscous force acting on a spherical body of radius 'r' moving with velocity 'v' in viscous media of viscosity 'η' is given by,
F= – 6πηrv.

In which liquid, the terminal velocity of an object will have lesser value-benzene or honey?
The terminal velocity of honey will be lesser because the coefficient of viscosity of honey is greater than that of benzene.
Is it necessary to apply some driving force to maintain the flow of liquid through pipe?
Yes, it is necessary to apply some driving force to maintain the flow of liquid through the pipe. The viscous force between the different layers of the liquid will retard the motion of the liquid and flow stops after certain distance.

What is viscosity?
Viscosity is the property of the liquid by virtue of which it opposes the relative motion between its different layers.
The resistance to the flow of liquid is also called viscosity.
