What is viscocity |
|
Answer» Viscosity is that characteristics ot flowing by virtue of which it opposes the relative motion between adjacent layers of flowing 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.Viscosity arises due to the strong intermolecular forces between the molecules that holds them together and resist the passing of layers over other.The layers of molecules of the flowing liquid that are in contact with the surface are stationary.Increase in the distance between the two layers increases the velocity of the upper layer. |
