Answer: The SI unit of Viscosity is pascal-second.
Viscosity is the frictional force between adjacent layers of fluid in a relative motion. It curbs the flow of liquid in injection molding, spraying, and surface coating. It can be classified into three types Kinematic viscosity, Dynamic viscosity, and General viscosity. Viscosity depends upon the temperature, pressure, and rate of deformation of a liquid. In superfluids, the viscosity is zero at very low temperatures. Such fluids are called ideal or inviscid.
What is the SI unit of Viscosity?
The SI unit of Viscosity is newton-second per square meter (N·s/m2) or Pascal-Second. Fluidity is the reciprocal of viscosity.
