WebSep 12, 2014 · Eta is the viscosity. So this is the viscosity of the fluid. And the volume flow rate's inversely proportional to the viscosity because the more viscous the fluid, the more it resists flowing, and the less meters cube you'll get per second. And it's inversely proportional also to the length of the tube. WebDynamic vs. Kinematic Viscosity. The absolute or dynamic viscosity is the ratio of shear stress to shear strain. The dynamic viscosity divided by the density of the fluid gives kinematic viscosity. The dynamic viscosity measures the resistance offered by the fluid to the flow when an external force is applied. the hudaacademy.org
