Difference:
⇒Viscous force depends on the velocity gradient and area of contact and frictional force independent of area of contact and relative velocity.
⇒Viscosity of liquid decrease with increase in temperature, Where as friction independent of temperature.
⇒In friction heat is generated at the surface between the solids. When a fluid moves over a solid heat is generated within the fluid.
