Then,... WebNewton’s Law of Viscosity What is viscosity? Viscosity is a physical property of fluids (liquids and gasses) that pretty much measures their resistance to flow. On a more fundamental level, the term “flow” refers to molecules moving along due to some net force. The more a fluid is able to withstand that force, the greater its viscosity. diana shopping oradea

From equation 1, we can say that the effort required to move fluid (like pouring) depends on its viscous nature, labeled by η or coefficient of viscosity. Honey has a higher value of η than that of water, hence pouring honey needs a little more effort compared to pouring water.
