What is a viscosity? |
|
Answer» Viscosity is the measure of internal friction of a liquid.This friction arises between different layers of a liquid and offers resistance to the flow of the liquid.Greater is the friction, greater is the amount of force required to cause the movement of liquid.Highly viscous fluids have more fraiction than less viscous fluids.The SI units of viscosity are Kg/ms or Pa s. Molecular force of attraction between the molecules of a fluid Viscosity refers to the resistance to the flow of liquid arising as a result of the internal friction within the layers as they pass over other layer. |
