Fluid dynamic viscosity formula
Webμ (some authors use the symbol η) is the dynamic viscosity ( Pascal -seconds, kg m −1 s −1 ); R is the radius of the spherical object (meters); v is the flow velocity relative to the object (meters per second). Stokes' law makes the following assumptions for the behavior of a particle in a fluid: Laminar flow Spherical particles WebJul 11, 2024 · Based on the physiological state of coronary artery vessels and the actual blood parameters, the blood inlet velocity, dynamic viscosity, and blood density were set to 0.12 m/s, 3.572 mPa·s, and 1100 kg/m 3, respectively. The essence of blood is an incompressible non-Newtonian fluid.
