Dynamic viscosity refers to the viscous property within a fluid that hinders its flow, manifested as the degree of frictional resistance between different layers of the fluid under the action of external forces. Dynamic viscosity is defined as the ratio of shear stress between fluid layers to the velocity gradient, and its unit is generally pascal-second (Pa·s). .
