Viscosity is a measure of a fluid's charge-dependent resistance to a change in shape or to movement of its neighboring portions relative to one another. For liquids, it corresponds to the informal idea of thickness; for example, branch cutting shears syrup has the next viscosity than water. Viscosity is outlined scientifically as a drive multiplied by a time divided by an space. Thus its SI items are newton-seconds per metre squared, or branch cutting shears pascal-seconds. Viscosity quantifies the inner frictional pressure between adjoining layers of fluid which can be in relative movement.
