Web27. feb 2014 · The dynamic viscosity \mu measures the fluid’s resistance to shearing in the fluid. It is the constant that relates stress to velocity gradients. The dynamic viscosity is related to the kinematic viscosity \nu by the relation \mu = \rho_0 \: \nu. The symbol for the dynamic viscosity \eta is also sometimes used. Bulk viscosity, \mu_\textrm{B} WebREFPROP is based on the most accurate pure fluid and mixture models currently available.
