Viscosity is a measure that states the thick of a liquid or fluid. Viscosity is the nature of the fluid that is closely related with the obstacles to flow, like a liquid flowing in a rapid, water, alcohol, and gasoline. And the liquid flows slowly like glycerin and honey because the viscosity is great, so no other viscosity determines the speed of the flow of a fluid (Rao and Rizvi, 1995; Ahmad, 2007).
