WebThe SI unit for dynamic viscosity η is the Pascal-second (Pa-s), which corresponds to the force (N) per unit area (m 2) divided by the rate of shear (s-1). Just as in the definition of viscosity! However, since the viscosity of most fluids is below 1 Pa-s (See Table 1), the millipascal-second (mPa-s) is often used instead. Note that 1 mPa-s is ...
