WebApr 12, 2024 · Viscosity is an important rheological property for modeling blood flow. For the effective viscosity of suspension flow, dependent on the particle concentration or hematocrit (ϕ), various empirical correlations are available in the literature. 47–49 47. A. J. WebSimilarly, if the viscosity of the blood increases 2-fold, the resistance to flow will increase 2 fold. In contrast, an increase in diameter (or radius) reduces resistance. The change in diameter alters resistance to the fourth power of the change in diameter. For example, a 2-fold increase in diameter decreases resistance by 16-fold!
